I first heard about them here on the board and saw some posted pics. They look nice and I've read how handy they are as totes for class items. I can understand why people that like to have a bag or purse co-ordinate with their outfits would like them since they are easy to make, and look nice.
But I have so many tote bags some free that I use those and I generally don't switch my purse day to day, and I really want one that has a zipper closure for at least where I have wallet etc. for security. So I'm not sure I'll ever make one either but they are nice for those that do want them.
