Resource Library: Choosing the Right Needle.

Being confused by which needle you need to use is a very common problem among new and some old sewers.
So don't get discouraged!
With so many different numbers and fabrics to choose from it can make you quite uncertain of the correct needle for your specific project.
But don't worry! We're going to break it down for you and help you learn the basics about sewing machine needles.


 Let's start with the anatomy of a sewing machine needle.



Needle Anatomy from Threads:
http://www.threadsmagazine.com/item/3751/machine-needle-know-how


Shank: Top portion of the needle, usually having a flat back, that is inserted into the sewing machine with the flat slide facing the back. Needle is tightened into place with a screw on the machine. 


Shaft: The body of the needle determining the needle size based on the width of the shaft.


Front Groove: Slit above the eye that allows the thread to be flat against the needle.


Point: Tip of the needle that penetrates the fabric and forms the stitch with the bobbin thread. Shape of point varies between needles. Important to pay attention to when choosing a needle for your fabric.


Scarf: Indentation on the back of the needle that helps eliminate skipped stitches. A longer scarf is preferred.


Eye: The hole at the tip of the needle that allows thread to pass through. Eye size changes with the needle.



Needles range from size 8-18. These numbers are corresponded with the European needle sizes 60-120 on the packages. So for a pack that says 70/10, the 70 is the European needle size and the 10 is the American size.

The smaller the number, the smaller the size.
That size is relavent to the weight of your fabric. For sheer materials such as chiffon, you would want to select the smallest needle size. For a heavy weight outdoor canvas, you would want to use the largest needle.  

Below is a basic needle size chart I found on the blog Presser Foot.


Easy enough right?
But wait! Before you begin sewing we must discuss the point of the needle!

Here is a great picture of needle points from Sew-What's-New




Univeral: Slightly rounded point that you can use on knits or wovens, hence why they are called universal. So if you are completely baffled by which needle point to use, begin with this one.


Jersey/Ball Point: This medium tip is slightly rounded to pass between the threads rather than pierce them which can create runs in your light weight knit fabric. A ball point needle will not damage the spandex in knits. Using these needles on heavier knits helps creates even stitches.


Stretch: This needle features a deep scarf so the bobbin hook can get closer to the needle and prevent skipped stitches when sewing on fine lighweight knits such as silk jersey or highly elastic knits. Use this needle when you are experienced skipped stitches with the ball-point needle.


Jeans/Denim: This needle has a thick shaft and a very sharp point. Ideal for sewing denim, canvas, or tightly woven fabrics. 


Microtex/Sharp: This needle has a narrow shaft and a sharp point to piece the threads of woven fabrics. Use for stitching finely woven fabrics such as silk, lightweight suede and microfiber fabrics. The sharp point also helps enable perfectly straight stitching which makes them great for topstitching!


Leather: This tip is wedge-shaped with allows it to penetrate leather, suede, and vinyl without tearing them.


Self-threading: The eye has a slot on the one side so you can easily slide the thread when you are having trouble threading a regular needle. This needle works best on wovens, but tends to snag knits.


All the above information can be found on this great chart I highly recommend you print out and refer to when you need some quick help!

Made by a Fabricista: Summer DIY Print Mixing

Hello Gems! It's still summer and it's a hot one! I'm not a shorts and t-shirts type of gal, as you all may know by now. That is, unless the occasion calls for it of course! I'm more of a casual chic, flirty two piece, with a little bohemian vibe on top type of gal! So you can find me beating the heat in these last days of summer in this cool and comfy backless tiered flounce sundress. Oh, and let's not forget the puff sleeves!  This whole vibe sums up the summer! And nothing says it better than zebra and tribal print! I coordinated the rayon rugged Tribal print crinkle challis with this rayon zebra print challis. These two prints look absolutely amazing together. They are both very drapey fluid fabrics that fair well as summer garments. They are breathable and feel so light and cool against the skin. Challis fabrics make great flounce and it's not too light weight that you have to line it. I absolutely adore both of these prints. Zebra print is one of those pr

Made by a Fabricista: Fast Sews and Cool Summer Fabrics

Happy Friday everyone! Today I'm sharing a few things made with my favorite summer fabrics - cotton, linen and rayon - and as an added bonus these are all super quick sews. Each of these projects took me no more than 2-3 hours to sew. My house gets too hot to sew some summer days, so projects I can whip up quickly are great for that limited amount of time that I have.  The first two items I made up as a set, but of course they can also be worn as separates. The top is the I Am Patterns Gaia tank made with a stunningly gorgeous cotton challis. Call me naive but I had no idea cotton challis was even an option! I'd only ever seen challis in rayon. This cotton though is simply a dream to work with, and if you run across it I highly suggest snagging some. The top is a simple V-neck with a facing but what makes it special are the gathers at the shoulder, made by simply adding a bit of ribbon or fabric in a tube. The combination of this pattern with this light cotton fabric is the per

Made by a Fabricista: Summer Ain’t Over Yet

All of my fellow Fabricistas have been looking toward starting their fall wardrobes. But this year, I’m riding my summer vibes right until their official end in mid-September, because I’m doing something a little different: going on a beach vacation after Labor Day! Now is as good a time as any to tackle my first swimsuit, and I have to say, it was a great experience. And of course, I’d need a cover-up too. Fabric Mart had everything I needed to try my hand at a swim suit. I knew I wanted a bright, colorful patterned suit that was more likely to hide any construction flaws, so I picked this really fun nylon/lycra and it just screamed summer fun. Since I wasn’t sure which lining would work best, I ended up picking up the plain black swimsuit fabric to line with, since I read that you can line with swim fabric. It ended up being thicker than I imagined, but for me, I felt like this worked great because the recovery of the two fabrics together is excellent. The fabric is great quality. I
