I buy sewing machine thread in the colors I use most often in bulk by the serger cone. I use stand alone bobbin winder like this one to wind the cone thread onto an empty regular size thread spool to use on my sewing machine. (Disclosure: I am including affiliate links for your convenience.) This is supposed to keep me from running out of thread but when my historical costuming projects usually take up to 10 yards of fabric I still go through a ton of sewing thread.
Which means I have a nice little stack of empty thread cones on my To Upcycle shelf waiting for a craft project that never comes.
I recycled empty thread cones into cute little gnomes. If you don’t have empty thread or serger cones
cluttering up your house waiting to be upcycled you can use paper craft cones like these.
You will need for each gnome you want to make:
