Is it possible to use a circular needle as a stitch holder?
Yep, that's why they have those plastic caps in the sets.
I frequently have several circs in my knitting as holders. Either that or yarn for a lot of stitches.
I just thread a contrasting color yarn through the stitches and tie the ends together. Works for me.
I even use a paper clip. Those are great, you just shape them to whatever you need.
That was my next thought! Great minds think alike! :teehee:
I just used that way, because I always misplace my stitch holders, so this way, I always have one with me.
