Not too long after Christmas I made this bag to hold the pieces of Andrew’s “saxoflute.” For those who haven’t seen a saxoflute, it’s a bunch of pieces that you can put together in different ways to make your own instrument – quite cool! I think this was my first (or possibly second) attempt at a double drawstring bag, and it turned out quite well!
I’ve been continuing to work on my formula for cutting sizes needed to get a bag of a certain size. Here’s the “formula in progress” for a two panel (front and back are sewn together on both sides, rather than being one piece of fabric folded along one of the sides) bag:
finished height = panel height – .5D -.75″ where D is the depth of the bottom of the bag
The additional .75″ loss is from the .5″ seam allowance at the bottom and the .25″ seam allowance at the top.
finished width = panel width – .5D – 1″ where D is the depth of the bottom of the bag
The additional 1″ width loss is from .5″ seams on each side.
Any topologists want to comment on my formula?
