Mattress stitch is a way to seam together pieces of knitting. To make this process as easy as possible, block the pieces to be seamed and use a sturdy, contrasting yarn as your seaming yarn.
Once you get the hang of Mattress Stitch, you can use the tail yarn of your project to do it (this is slightly more challenging because the yarn won’t stand out as you work).
- On the upper piece, insert the tapestry needle under both legs of the bottom-right-most stitch you can find. Pull the yarn through.
- On the lower piece, insert your tapestry needle under both legs of the top-rightmost stitch you can find. Pull the yarn through.
- On the upper piece, insert your tapestry needle under the stitch next to the one you went under previously. Pull yarn through.
- Repeat steps 2-3 until entire edge is seamed.
