I loved this purse, and decided to make it. I went a little further - lined it, put a little pocket inside, crocheted the lime green swirl and handle to match the lining. I also put a snap. You can not see the snap on the picture, because I did it after I took pictures.
So here is my version of Snail Shell Beach Purse from Frugal Knitting house:
Here is their original version with a pattern:http://frugalknit12330.goeserv.com/homepage/snailpurse.htm
A couple recommendations, if you decide to make this purse:
1. Cast on really tight, and knit tight the first raw.
2. Loose it a little bit and bind off loose.
Otherwise the purse will not be flat like you see it on their picture. Instead of two circles ypu'll have two cones. I did not realize that first, and had to redo one coil.
