Even in today’s digital world, many of us still manage to collect and carry an assortment of cards. ID cards, credit cards, gift cards, membership cards, business cards…the list goes on. This MODULAR KNIT CASE is the perfect alternative to a bulky wallet that you toss into a bag. It can also hold a gift card that the recipient can later use to hold the rest of their cards. This small-scale knit is a great skill builder for join-as-you-go modular knitting. Once you have learned this technique on a small scale, a few quick calculations will have you knitting a case for everything you own.
