playing around with crochet gift card sleeves

20130517-105155.jpg

Last year I sewed a bunch of sleeves and wallets to give with gift cards. Since my sewing machine is still collecting dust, I decided this year to work on a crochet version.

I found a lot of cute patterns on Ravelry, both crochet and knit, but the ones I liked were written for a specific yarn weight. I want to use up little bits of leftovers for this project and don’t feel like dealing with gauge math for every single one.

So, I’m working on a formula, which I will share once I’ve got it figured out.

What are your favorite ways to give gift cards?
