I have found my sewing room feels like it is a disaster when I am cutting projects, have printed off patterns, acquire new fabric that must be introduced into the stash... If you can use one thing for two purposes, that will surely help. Storage bins?? Are they labeled? How many of them have you even opened in the last 6 months? So I am voting to sew and keep sewing. You most likey will empty a bin or two and see a few things along the way that you can PIF or toss.
