I made an assortment of these little storage bags for Christmas presents for my family members, made out of my father's old work jeans.
I simply cut off the legs, stitched across the bottoms, then stitched a box pleat across the side, just like when making these thread catchers.
My father still had a stack of brand new bandannas in his dresser drawer, so they worked perfectly for the linings. He always carried an old red bandanna in his pocket. :) I did interface the bandanna with a medium weight fusible interfacing to give the bags a bit more body.
I love the paint splotches....
Looking forward to giving these gifts to my family!
