So you’ve knitted all your pieces and your ready to sew them all together. For a new knitter, this can be pretty overwhelming. There’s nothing worse than spending hours and hours knitting, only to let it down with average finishing techniques.
When I finished knitting only my second ever jumper, a man sized jumper for my husband, I was not looking forward to seaming it. I searched all over the internet trying to find the best technique, but how do you search for something when you don’t even know what it’s called?
I ended up taking it to my LYS (local yarn store) to ask them. They advised me to just use running stitch. However, I knew there had to be another way. Finally I came across Mattress Stitch on the internet, an invisible seam for stocking stitch. This was exactly what I had been looking for! So are you ready to learn this amazing technique? It is quite easily the best technique you’ll ever learn. I only wish I had learnt it earlier. It even makes seaming your projects kind of enjoyable!
As mentioned above, mattress stitch is a technique used to join two pieces of stocking stitch together, leaving an invisible vertical seam. Perfect for those super long side and sleeve seams.
To start, lay the two pieces of knitting you want to seam side by side with the right sides facing up. Gently pull apart the first and second stitches on the bottom row of your first piece of knitting, to locate the running thread. Running threads are the series of horizontal bars connecting each stitch, see the first image below.
Using either a tail end, or a new piece of yarn, insert your needle under the running thread between the first and second stitch on the bottom row, and repeat on the opposing piece of knitting.
Continue working back and forth, occasionally pulling the yarn firmly through the stitches, keeping an even tension. See images 2 & 3.
This is my biggest tip when shaping sleeves: Knit one stitch at each end of the row before/after adding your increase stitches. That way you can seam the sleeves using mattress stitch without worrying about your increase stitches getting in the way. This makes seaming not only easier & quicker, but also neater too!
