sure, I'll share. I don't know if I speak the lingo correctly so follow along as best you can...
1 towel
1/2yd print. fold in half and square the other 3 edges...yes, it's 2 layers...it just seemed more durable that way.
nylon straps, cut evenly, don't forget to burn edges so they don't unravel.
turn over fabric where the fold is...about an inch or so of a hem and pin with one nylon strap with edges about 10in apart on the outside measurement. or however far apart you want them. Double stitch(2 visable stitches that run along side each other) along the top and bottom (crossing over the nylon strapping.) This will make that nice finished edge/look to the outside of the bag...it's a cosmetic thing.
Then triple stitch(here i mean criss cross then go backwards over the same line etc) a criss cross on the nylon strap...
Center this peice on your towel and pin the other nylon strap to the towel, lining up the nylon straps so that they match up when being carried, kwim. Pin, then, Triple stitch the nylon strap onto the towel...i criss crossed and sewed straight across top and bottom for good measure
now lay the printed fabric peice and towel peice together with the straps together...iow, when you carry it, you want the straps on the outside...or at least i did. so whichever part you want to be on the outside of the bags, those are the sides you want together.
I folded over and double stitched all the way around the fabric peice. To hide the unfinished edges, you could double fold them.
turn bag inside out and stuff towel inside.
