1st: Finding this board. =)
2nd: I use those mole strips that you buy that are sticky on the underside for my 1/4" seam. I just cut a strip and stick it down. Works great!
3rd: I cut my blocks while watching t.v. with dh and safety pin together so when I am ready to sew I just take a stack and lay them all out and sew. This way I can have several ready to go and just sew them up all at once.
4th: I have extra bobbins all ready to go when I get ready to sew. This keeps you going for quite a while without having to stop, wind the bobbin and rethread.
5th: I have a box under my table that I use to cut my fabric and all of my itty bitty scraps go in there when done so there's not a huge clean up needed. The larger pieces go into another container on the table for scrappy stuff. (clean up as you go and there's more time for sewing)
I am still very green so these may be so little to others but they have helped me. With very little time to sew these are big time savers for me.
