My handmade leather thimble for my thumb....I can't hand sew without this little guy! If I have alot of hand sewing to do, then I wrap my fingers in "gentle tape" used for your skin and can be found in the drug stores. It comes in a scotch tape like dispenser. Give a little added protection to your skin but also gives you movement.
A small needle and a large long needle for hand sewing; the long needle for sewing eyes on.
A needle nose pliers with the blue handle is mostly for jointing but also a great tool to grab and pull a needle through thicker fabrics when hand sewing.
A screwdriver for jointing as well as the tool with the yellow & black handle for holding locknuts.
What's your "tools of the trade"? Or your most favorite tool you can't live without?
