Final measurements on it were 15 1/4” height x 22 1/4 “ length x 6”;wide, support straps are under a yard each, handles are around 18” each, then interior pockets and exterior pocket. So a lot. I had alot of it as left overs.
Hoping it lasts a lifetime, if not hers at least mine as it took some time to hand-stitch interior and exterior and finish bag.
