I've made backpacks before, but making from new fabric, you have much more freedom as you're not limited to sizes. As it turned out, Daniel had wanted a small backpack, so he was doubly happy.
To back the straps and line the inside, I've used a pair of trousers that I had in my fabric box. They had been Daniels, but he put the knee through falling over. These were smart trousers and patching wasn't an option. The whole knee was worn. It's like they've been waiting for this project. I just love the way they've worked for the inside.
If Daniel hadn't liked the bag, I'd have been happy to have kept it for myself. He loves it and thinks I should make more. I've actually got a tartan dress in my fabric box, I just need to find the right jumper to felt!
