What is a Moss Stitch Envelope Border?
First, an envelope border is made by crocheting 4-5 border rounds on the front and back of a blanket. So, you have two pieces of crocheted fabric to seam together in a final round. As you stitch the final round, the ends from the overlay mosaic blanket are tucked inside the pocket.
There are many different stitch variations you can use for an envelope border. For the Spooky Season Mosaic Blanket, I chose the Moss Stitch. Not only is it one of my favorite stitches, but it’s easy to highlight all four colors used in the blanket.
Why you’ll love the Moss Stitch Envelope Border
- Quick working to finish your blanket
- Looks great with alternating colors
- Beginner friendly + avoids crocheting over the ends

Written Instructions for the Moss Stitch Envelope Border
An envelope border creates a “pocket” to hide all the yarn ends instead of weaving them into the blanket. You will crochet a front and back panel. Then, seam it together with single crochet stitches. Each panel consists of four rounds before the fifth round to join the panels.
This specific envelope border uses the Moss Stitch. Do not crochet tight! You may need to size up one hook size to prevent tight stitching. Alternatively, you can substitute the Moss Stitch with the Single Crochet Stitch.
Preparing the Blanket
Once you’re finished with the blanket, you need to prep the ends before creating the envelope border. Securely tie two ends together, and trim the ends down to 1-2″ long.
