I use three of them! :)

Meat wrappers brown one side, and wax other side for applique, and dollar store placemats for template, in lieu of mylard. Electric can opener place by my sewing, it has a magnet for pins, as I remove from fabric just toss up and it holds them.. Then, I have opener ready for lunch.

I use wooden clothespins (the kind with the spring, not the antique ones) when I'm sewing on my binding; I've almost stopped using pins and instead use Elmer's glue; and I use a chopstick or skewers for lots of miscellaneous tasks.

Oh, and I store my thread and bobbins in a tackle box!

I use tweezers to pull the really short bobbin thread up after using the thread cutter on my sewing machine.

Those are such great ideas! The only one I can think to add is I use coffee filters for stabilizer for machine applique.....cheap and acid free.

I like to use painters tape for marking quilting lines. Also, the silverware insert for drawers makes a nice organizer for log cabin pieces.

Tonight I was looking for something to use to hang a small wallhanging that has a 1/4 " wooden dowel in a fabric sleeve.
I found a pretty eyeglass chain/holder, slipped the rubber ends over the dowel ends - voila! Quilt hanger!

I use bobby pins instead of pins or glue when binding a quilt.

My DH is a machinist by trade... and he brought home a really heavy-duty tool box to clean up so he could sell it. I wouldn't let him - I'm using it as MY sewing/quilting tool box. Spools of thread (even some of the larger ones) in the top, and lots of various sized drawers for all kinds of things. It's not going to break like the plastic ones, or tip over like the plastic ones, or get brittle like the plastic ones (gee, do you see a theme here?).
And another great thing (now that we have a new grandbaby arriving soon) is the drawers all LOCK ... with a real key, no less.
BTW, I "confiscated" this from him when we first got married... that's been 31 years now.
