So finally, after a trip to the fabric store, I found a fabric I think I can be proud of. I didn't recognize the type of fabric, but it was on the shelf with canvas and duck cloth, though it's not AS stiff.
And instead of one large pocket inside, with seemed too flimsy and everything fell out of it even though I could close it with a button on the previous one, I made two smaller pockets instead, which have held everything so far.
So can I finally put my purse pattern away for awhile? Will this one last?
