Frequently Asked Questions

Is this pattern beginner friendly?

Advanced beginners who are comfortable with double crochet and counting stitch repeats should have no trouble completing this project.

Can I make it larger?

Yes. Simply start with any foundation chain that is a multiple of 12 + 3 and continue repeating the shell rows until your desired size is reached.

Does this stitch use a lot of yarn?

The raised shell texture uses slightly more yarn than basic stitches, but the luxurious look and cozy feel make it well worth the extra yardage.

Can I use bulky yarn?

Absolutely. Using bulky yarn with a larger hook creates a wonderfully plush blanket and works up much faster.
