now this is what I like to see
actual effort and just DOING and adapting along the way instead of planning and planning and doing nothing.
if you sat and thought about this and tried to make drawings and plan the whole thing out, you'd probably still be doing just that---AND asking peoples questions and opinions about what's the "right way" to do something while accomplishing nothing.
VERY GOOD WORK---and extremely practical idea on the belows---a quick fix for all of us who may need something that works in a pinch---say if you send out your bellows to get new ones made--you DO need something temporary in the meantime.
this gives me so many ideas....and it's inspiring.
