Would you like to make a DIY Backpack? Below you'll see our plans for a DIY Backpack. This is still a work in progress, but we wanted to make available what we have put together so far. DIY Backpacks are not as hard as they look initially, but it is still quite a project to undertake. Be sure to think through each step before hitting the sewing machine with your cutouts. The suggested materials for this project are only suggestions.
