I started this over on the OOT thread but it's definitely a DIY too! I couldn't find any beach bags I liked at the right price, so my friend and I are sewing them ourselves. We got the first one done last night, and I love the way it turned out. It's going to end up being about $4.50-$5 per bag (plus the endless hours of labor, but no one is paying us for that!). I put a magazine and water bottle in it to test it out, so that's what you can sort of see through the bag.
