This beautiful, large bag is so roomy and durable! The pattern is clearly written with step by step instructions and lots of photos. Using very basic stitches - single crochet and double crochet- the bottom half of the bag is done in single crochet to produce a tighter fabric in order to securely hold your contents in the bag. The top of the bag is done in a beautiful array of double crochets & single crochets that produce a lacy shell pattern. The shoulder strap is folded lengthwise; this discourages the strap from stretching out too much when the contents of the bag are heavy. I"m happy to help if you have any questions please don't hesitate to reach out. I hope you enjoy this pattern as much as I did! Have fun! And don't forget to tag me in your social media photos and posts, I LOVE seeing the items you create using my patterns!
