So I did a little test for a customer and decided to share it with you. Here is the original listing of lightly filled bag (turquoise, 100% cotton yarn, no lining):
The photos below are of the same crochet bag filled with the 4 items that have a combined weight of 3lbs 6oz:
1. a thin beach towel 53" by 27",
2. a standard water bottle 16.9 fl oz/ 500ml,
3. a paperback book about 8"x5"1", 285 pages
4. a large wallet.
There is still room for some more.
The crochet tote pictured above is about 23 1/2" tall from the top of the handle to the bottom of the bag and the tote's body is about 13" tall and 13" wide (when it lays flat).
