I started on a carry/storage bag for a bow trainer called an Accubow;
AccubowIt can be safely drawn and released without an arrow, making it useful to home practice. But I’ve got to store it when it’s not in use. I have a big piece of soft magenta leather that I am using to make a storage bag.
So far, I have cut the pieces, sewn on a pocket and sewn the front & back together. I have also made the box pleats. I still need to put a bunch of snaps across the top & sew on the straps. I will be using nylon webbing (I didn’t have enough of the magenta leather to make straps.
This has been challenging as it is the biggest thing I have sewn from leather. Also, making the box pleats meant sewing across thick seams. What worked was just turning the hand wheel & going one stitch at a time, over the thickest parts.
