Made By A Fabricista: Tips for Sewing The Jasika Blazer

Sometimes you just bite off more than you can chew and that happened to me with The Jasika Blazer from Closet Core Patterns.  What I would like to write is that The Jasika Blazer is a classic and versatile jacket that can be dressed up or down depending on the occasion. But I can’t because it is still in pieces!!  It happens and that’s is ok. Sometimes we don’t have as much time to sew as we would like. I did get to one of the key design features of this blazer, welt pockets, which can seem daunting for those new to sewing. In this blog post, I will give a brief break down of the process of sewing welt pockets and also provide tips on how to iron velvety no wale corduroy fabric courtesy of Fabric Mart Fabrics.

Price of the Project

First I do want to be up front on the cost of this project.  It is not a cheap. The total cost of the materials for the Jasika Blazer project would be $144.95. The outer fabric was $24.99 per yard, and three yards were purchased, bringing the total cost to $74.97. The lining fabric was $14.99 per yard, and two yards were purchased, making the total cost $29.98. Finally, the interfacing kit was $40.00. It's worth noting that the cost of the materials may vary depending on where they were purchased and if any sales or discounts were applied. Additionally, other expenses such as thread, buttons, and other notions should also be considered when calculating the total cost of the project. With all that said I do consider this project a wearable muslin, wearable when it will be totally finished.  I did start out with cheaper fabric because I sew a lot of Closet Core Patterns and the sizing is very consistent for me.  I’m saying it is a muslin because I would like to improve some of the techniques that are applied to this pattern. They include hand stitching and the welt pockets. 

Ironing interfacing


The interfacing kit from Closet Core consists of weft interacting, knit interfacing, horse hair canvas, sleeve heads and shoulder pads.  Interfacing all the fabric took a considerable amount of time.  Due to the fact that the fabric I chose had stretch I had a lot of problems with the interfacing staying in place after being ironed.  So if you plan on making your own Jasika Blazer do not use a fabric with any stretch.  Also protect your iron with a piece of cotton when ironing so the glue doesn’t get stuck to your iron plate. 

Sewing Welt Pockets

Welt pockets are a type of pocket that lies flat against the garment and is finished with a strip of fabric called a welt. They are a sophisticated and professional-looking pocket that is commonly found in men's tailoring but can also be incorporated into women's garments such as blazers, jackets, and trousers.


To sew welt pockets, you will need to follow the pattern instructions carefully and mark out the pocket placement using tailors tacks on your fabric. The Jasika Blazer pattern provides detailed instructions on how to sew welt pockets, including diagrams and photos to help guide you through the process. It also goes into great detail about speed tailoring and hand stitching. 

Here is a general overview of the steps involved in sewing welt pockets:

1. Cut out the pocket bag and welt pieces according to the pattern instructions.

2. Interface the pocket bag pieces to add stability and structure.


3. Sew the welt to the garment front, using the markings provided in the pattern as a guide.

4. Cut through the garment front between the two welt seams and carefully clip the corners (this part can feel so scary).

5. Fold the welt back and press it flat.

6. Attach the pocket bag to the welt and stitch around the edges to secure it in place.

7. Fold the pocket bag up and press it flat.

8. Topstitch around the welt to finish.

Sewing welt pockets can be challenging, but with practice and patience, you can achieve a professional-looking result that will elevate your garment. I have sewn welt pockets before but it has been a long time, I will be trying them again when I make another blazer. 

Ironing Velvety Fabric


Corduroy and velvety fabric can be great options for this blazer. However, it can be tricky to iron, as the pile can become crushed and flattened if not handled carefully. Here are some tips for ironing velvet fabric:

1. Set your iron to a low heat and turn off the steam function.

2. Place a pressing cloth over the velvet fabric to protect it from direct heat or place the velvet on another piece of velvet, face to face and press.

3. Gently press the iron onto the fabric, moving it back and forth in a sweeping motion.

4. Do not press down too hard or leave the iron in one place for too long, as this can crush the pile.

5. If the velvet fabric has become crushed or flattened, you can try steaming it with a garment steamer to restore the pile.

6. Hang the velvet blazer or jacket on a sturdy hanger to prevent the fabric from becoming crushed.

By following these tips, you can iron velvet fabric without damaging it and keep your Jasika Blazer looking its best.

In conclusion, the Jasika Blazer sewing pattern from Closet Core Patterns is a great project for those looking to improve their sewing skills and create a classic and versatile garment. Sewing welt pockets can seem intimidating at first, but with practice and patience, you can achieve a professional-looking result. Additionally, knowing how to iron velvet fabric properly can help you maintain the luxurious look and feel of your blazer or jacket.  And remember to take your time.  This pattern is not a speedy sewing project.  So in the next week or two I do hope to complete it fully and post the finally photos to my Instagram account!  Follow me there at ModistraSews, happy sewing!

Made By A Fabricista: A matching set and a happy error.

 Hi sewing friends! Today I’m sharing a new outfit I made inspired by looks I’ve been seeing pop up in my Facebook and IG feeds a LOT this year. I’m talking about those monochromatic matching top and bottom outfits, sometimes in linen, sometimes in a flowy knit - the ones that advertise they go effortlessly from loungewear to office wear to going out wear. So I decided to “sew the look” using Fabric Mart fabric and a few patterns I already in my massive pattern library. First, let me share that I have very few solid color pieces in my closet. I’m so taken in by whimsy and geometric prints that this is still a gaping hole in my wardrobe -  a matching solid color set was actually a practical addition for me.  So let me walk you through how I created this look, and also tip you off to an error I made while cutting that worked out pretty well after all. Can you spot the error? Hint - it’s somewhere in the top: Here’s how I went about building my matchy match outfit. And here’...

Made By A Fabricista: Birthday Dress

May is my absolute favorite month, we get to enjoy spring weather and it is my birth month.  The birthstone for May is Emerald. I think emerald is such a gorgeous color so when I saw this beautiful ombre charmeuse I thought it would be the perfect fabric to make for my birthday dress.  To be honest it took me a while to narrow down on a design.  After a lot of back and forth I ended up going back to my first sketch that I created. I love to sketch out my ideas to figure out the patterning and materials. To create the design I used the method of draping on my dressform.  I used the lightweight muslin that Fabric Mart offers.  It is always best to use a muslin or material similar to your final fabric.  I started first by marking my style lines with some draping tape on my dress form.  I tore out pieces of muslin to fit within those lines making sure I am always marking my grainline. I also used the muslin to determine how I will create the rosettes onto...

Made By A Fabricista: 3D Florals Meet Polka Dot Charm: A Look That Transitions With Style

When I saw a sleek pink mini skirt adorned with a dramatic 3D flower on Pinterest, I was immediately inspired. It had that perfect balance of playfulness and polish—something I knew I wanted to recreate with my own spin. Rather than replicate the exact look, I adapted the silhouette into something more wearable for my lifestyle using a vibrant stretch tweed fabric from Fabric Mart. The Skirt: From Pinterest to Personalized For my version, I used Butterick 5446—a tried-and-true pencil skirt pattern—as the base. I swapped out the smooth fabric from the inspiration for a neon stretch tweed, which adds structure and visual texture while still being comfortable to wear. The oversized flower detail is what makes this piece stand out, and it was surprisingly simple to make. I found a quick and easy tutorial on Instagram for how to create petal shapes and build a dimensional flower. There are also plenty of resources on YouTube that break the process down step by step. Once you’ve got the tec...
