When you need to connect two pieces of stockinette stitch vertically then you can use the mattress stitch. The mattress stitch gives seamless look to the fabric. It is an easy and adequate way for sewing seams of the sweater, or any other seams or blanket squares that need to disappear in the final project.
This is a simple stitch that is suitable for beginners too. It is a quick and easy way to sew up a seam. When the project finishes you can only know the seam and you have to feel it in the fabric.
- Knitting sewing needle
- 2 knitted pieces to join
- Matching yarn
Start the Stitch
The mattress stitch can be worked in a whole stitch or half stitch from the end of the knitting. Sewing a full stitch in is much easier and you need not work with the problematic edge stitches.
Begin knitting by gently pulling between the first and second row. You can see a little bars series that run between the stitches. These are used to stitch the pieces all together. Slide sewing needle under the first bar.
Start the Seam
Find the first bar on the second knitting piece as on the first. Work the stitch again by going under the bar. Until you work on some stitches on every side you need to continue in the same manner. Pull the yarn as you go.
Rework on a Missed Stitch
The best thing about the mattress stitch is that it can be pulled out easily and simple to rework if a stitch is missed or you do not like the way it looks. By backing up you will not damage knitted fabric pieces.
Remove the needle from the yarn and separate the knit fabric pieces so the seaming yarn has a slack. Use the needle to pull the last mattress stitches and draw the yarn tailback. You should continue this until you reach the problem spot.
Pull the knit stitches gently on both fabric pieces so they go back to their original shape before initiating again with the mattress stitch. Inspect your seam for any missed stitches so you can work on them. It can be frustrating to spot the mistake once you finish the entire seam and it is worst when the sweater is assembled completely.
End the Seam
Pull the working yarn more tightly once you have done few stitches and the seam closes up magically giving the continuous look to the two distinct pieces. In the direction of the seam, you need to pull the yarn straight for the best outcome. Until the seam completes you need to continue in this manner.
Give the final tug to the working yarn when you are seaming the pieces together. In the end, weave in to make the seam secure.
