Recently, I challenged myself to design and sew a backpack. I used many stabilizers like sew in foam, decor bond and woven fusible to reinforce the backpack. When sewing with my BERNINA 560, I had no difficulty at all sewing through these bulky and thick layers. I also used my #12C Overlocker foot for piping on the backpack and my #4 zipper foot to add some functional zippered pockets to the backpack. With so many changes in feet during this project, it was quite easy to change a foot. The design of the feet make it easy to put the feet on and take them off quickly. I loved making this project on my BERNINA. I also sewed mesh pockets on and used fold over elastic. My machine had no difficulty at all with the different fabrics either. This backpack is a pattern design I am working on and my BERNINA makes it a joy to test my patterns and sew them up on it.
