Found this great bag pattern.http://laughingpurplegoldfish.com/2008/08/14/easy-peasy-crochet-bag/ Mine is 2 strands of Sugar & Creme held together & using a M (9mm) hook. It worked up really fast. I changed up the straps. Like on this bag,but bigger. http://tangledhappy.blogspot.com/2010/11/granny-stripe-boutique-bag.html I chained 40 then did 1 round of single crochet(us) around top & straps & 1 round sc on inside of each strap.
The closure is just ch & sc to make the loop.
