How many needles do you use during a project? Have you ever loaded up a needle for every colour? Do you use a new needle for every project or recycle your favorite needle?
Depends entirely on the size of the project. On a small project -- I use one needle. On larger projects -- I usually thread about three at a time.
I am fairly thrifty with needles and don't replace them unless I notice snagging or a break in the eye, or the hint of rust.
Right now, I'm using John James Petites #26. I had used the Piecemakers -- but not anymore.
