Mattress Stitch Tutorial

Place right side of project facing out or wrong sides together. Place yarn on your tapestry needle.

With the v’s of the top of your stitches lining up, bring needle from wrong side under the v’s and work back and forth across the stitches.

Continue working back and forth under the v’s from the wrong side of your project. Be sure to work in the stitches directly opposite of each other.

You may find it easier to keep a few of your stitches loose.

After a few stitches, tighten by pulling gently on your yarn.
