Go to Krogers (or any store that sells wine) they have a small reuseable bag that holds 2 wine bottles. I would take it apart & use it as a pattern. I buy the 99¢ reuseable bags at different stores (so I get different colors) & I quilt a panel to place on the front around the bottom & up the back. This makes my reuseable bags personalized. Everyone who sees them wants to know where I bought it. This is very easy & cheep to make. The kids use them as to carry their toys & coloring books. They make great overnight bags for them too. If you go to Joann Fabrics they have larger bags & if you have a Dick's Sporting Goods around you they have huge bags, my high schooler can put all his football uniform in it including his shoulder pads! That way he could hang it up & it wouldn't be laying all over his room.
