Resource Library: All About Knits

Have you ever wondered how knits are made? Well we've done all the research for you! Learn a little bit about how knits are made and the different types.

There are two methods used in producing fabric: Non-woven and Yarn Manipulation. Non-woven includes felting, bonding and interlocking fibers. Yarn manipulation includes: weaving, intertwining & twisting, and knitting. Weaving and knitting are the most popular methods being used in fashion, decor, medical, aviation, transportation and more.

Knitting Processes

Stitch or Loop in black

Knitting is a fabric production method done by drawing a yarn with a needle or hook needle into a loop from a previously done loop. (Just like if you were knitting yourself!) The smallest unit of a knit is a loop or stitch. A row of loops running selvedge to selvedge are called Course and a column of loops running with the selvedge are called Wale.

Knitted fabrics are divided into two different types: Warp Knitting such as tricot and Weft Knitted fabrics like jersey.


1. Warp Knitting: This type of knitting involves the drawn loops run with the selvedge along the length of the fabric. The warp yarns are prepared on beams. Milanese, raschel and tricot are warp knits.

Milanese Knitting: Warp knitting with a diagonal rib. Run-resistant.

Raschel Knitting: Can be made with intricate eyelet, lacy patterns, plain or jacquard patterns. Raschel knit fabric is coarser than other warp knit fabrics.


Tricot Knitting: Can be made with either single or double sets of yarns. Run-resistant.




2. Weft Knitting: This type of knit uses one thread running selvedge to selvedge making all of the loops in one course. Can be made in a Circular (using a cylinder) or Flat Machine. Is the most versatile method

Circular Knitting: The fabric is knitted in the form of a tube in a circular machine, the threads run around the fabric.


Flat Knitting: The fabric is knitted in a flat machine, the threads alternating back and forth across the fabric.



Weft Knitting fabrics include jersey and double-jersey (known as double-knit).

Types of Knits

Jersey Knit: Flat knit fabric are made with loops drawn from back to front, the face looks uniform, loops running in a course and wales with no interruptions. The ends curls up. The back of jersey looks like having wavy, fine ribs running selvedge to selvedge.

Double Knit: This type of knit is made from two layers of loops that cannot be separated. A double knit machine, which has two complete sets of needles, is required for this construction. The is made by needles drawing loops vertically and horizontally in each stitch.

Rib Knit: This is a type of double-knit fabric with wales alternately on the face and back. Odd wales on one side of the cloth and even wales on the back, making it look the same on both sides. It does not curl on the edges and have good elasticity selvedge to selvedge.
Interlock Knit: This type of knit is a variation of a 1x1 rib knit with flat and stable characteristics. It is not as flexible crosswise as a rib knit is.

 Ponte di Roma or Ponte Knit: This is another example of a double knit. The fabric is plain, looks the same on both sides and has flat, fine crosswise ribs. Ponti means bridge, full name would be Roman Bridge. The small units of double-stitches resembles a bridge. Ponte Knit is a versatile fabric, semi-flowy, light to medium, medium or even medium to heavy weight, suitable for working 3D designs on the apparel.

  1. What I would like to know is how to purchase knits with confidence. I get the different kinds of knits but there are so many different weights and I would like to be able to compare weights. Right now the information is usually light, medium or heavy weight. I imagine there is a huge range in "medium weight" fabric.

  2. Thank you for your comment! We will bring it up in our meeting about possibly doing an additional post to cover this topic. In the meantime, if you are planning on ordering fabric from Fabric Mart, you are welcome to call us and ask us questions about the knit you are looking at online. We understand that it is difficult to know if a fabric is right for your project when you can't see and feel it. And due to how quickly our fabric sells out, we do not offer samples. Please call us if you are unsure about our description.
    Thanks again!

  3. Great information. I was wondering if you could expand this to explain ITY knits. There are a lot of these for sale on your website, and I'm never sure what this means. Thanks.

Made By A Fabricista: Spring Ahead

Happy Spring!  We have finally made it into my favorite season which happens to also be my birthday season.  I feel like the New Year really starts in the spring season as everything comes back alive, and we all feel refreshed. So, for this post I created two separate looks to encompass my spring vibes. This first look I dared myself to create a look using two different prints.  I don’t work with prints often, but I had been really inspired lately by fellow Fabricista Marcia (keechiibstyle) who just has a magical way with mixing her prints. For this I used two different print jersey knits of 2yds each and McCall’s Pattern M8238 which allows for easy color blocking but in this case print mixing.  The fabric requirements call for a 2 way stretch but this knit worked just fine for the pattern. I love the contrast between the two prints.  This is the perfect spring style but can also but transitioned into summer as well. I did view C which had a high slit in the center.  Initially I planne

Made By A Fabricista: Summer Brunch looks just in time for Mother’s Day

Happy First Friday of May! I am truly excited that I have 22 more work days left before the summer break.  This school year has been a roller coaster ride and I have enjoyed some high moments and dealt with some low ones in between.  I wanted to start my summer looks early and decided to focus on looks I can wear when I visit Jamaica or other tropical places. These looks made are both great for Sunday brunch as well. This set is my first faux romper for this year and I love the fact that I can rock it as separates. When I came across this yellow graphite gray polyester fabric , I knew it was perfect for summer.  To top it off, I found the perfect matching earring from Purple Paradise Studio in lime (Rise stud in lime) and knew I wanted a chic summer faux romper set.  I decided to hack  McCalls 7943 dress pattern and create another top.  I have made it several times as I truly love it and plan to use this pattern as one of the beginner patterns for my summer sewing class. I have made it

Made By A Fabricista: The Summer Blues

People often speak of the “Winter Blues”, but today I bring you the “ Summer Blues ”, and it is all good news. Most people don’t think of blue as a summer color but personally for me any color is Summer ready depending on the style and fabric. The moment I seen this Polyester Lycra Diagonal Plaid Stripe Print DTY Knit (SYB8432) I knew I wanted to make something fun for the hot weather to come. I love the Navy/Black/Powder White mix of colors and prints all in one designed fabric. This DTY Knit is made up of 96% Polyester and 4% Lycra with a 4 Way Stretch. It has just the right amount of stretch but yet not too much to make it difficult to work with. If you used a pattern not calling for stretch fabric you definitely want to make adjustments when choosing your size.   With the different patterns in this fabric and made cutting it a breeze because I actually misjudged the amount of fabric, I needed but was able to cut the bodice in one direction and the skirt in another. That’s what I
