Send your little one off to celebrate Halloween in style with these easy-to-sew, fun-to-make Trick-or-Treat bags from WeAllSew.com. Spook them up with seasonal embroidery and use glow-in-the-dark embroidery thread for maximum effect. Don't have an embroidery machine? Just use a pre-printed panel cut to the right size. Need something a bit smaller for a party favor or gift bag? Then stitch up a cute mini version!
