I also would like to know that. I have lots of them.

I have a lot of bobbins, so I keep the thread on and use it in the top. If I start running out of empty bobbins, I just wind the thread onto an empty spool.

you can take all the threads unwind them and place them between layers of some type of sticky washaway stablizer and then you'll have a scrap of fabric (sortof) for applique etc. Saw this on t.v. but didn't pay a lot of attention. Of course I just pitch mine, there's usually not enough left to worry about.

Depends on how much is left. If it's really long then I keep it on the bobbin and use it for small parts of a design. The shorter pieces I save in a zip bag. I als save the threads that I cut off (jump stitches etc.) I use them with applique designs with a different twist. I stitch out the design but add a sheer fabric on top and the thread scraps sandwiched between. Really looks nice with some metalic threads added. Does that make sense?

I use for small sewing :o)

good question,flowers for you.

I do the same as bikermom, the result is then used for card making. I made some fantastic christmas cards using this method a few years ago

I do the same as Celticlady. I do not waste anything. I even glue or stitch stablizer together because of costs. H&*.

good ? I usually sit in front of the machine and wait for it to end...what a waste of time...talk about stingy!!
