When sewing large projects like messenger bags, totes, or duffle bags, add one of Annie's Acrylic Base Stabilizers to give your project more support. These acrylic stabilizers are 1/10" thick and help to create a more professionally finished look. They are durable enough that they won't break if you drop your bag and light enough not to weigh your bag down. To help protect the interior of your tote the bases have rounded edges that won't tear your fabric. Choose from five sizes: 4-1/4" x 11-1/4", 6" x 14-3/4", 6-1/2" x 18-1/2", 7-3/4" x 14-3/4", and 7-3/4" x 20-1/2".
