My mom had this great drawstring bag when I was a kid. She managed to save it through a robbery in Mexico! She passed it on to me eventually and I used it until it was shredded to bits. I loved that bag. Here's a little something I whipped up trying to replicate it. I'm not in love with the polka dots and I put the holes for the drawstring on the inside accidentally, but it was easy and fun to make.
I love a good ol' drawstring sack.
