I have always cut my lengths of thread roughly the same - used whatever, then used the leftover bits for confetti - or started cutting each strand of the 'normal' length to fit each time I needed 1 or 2 stitches - very tedious and frustrating.
I was looking at an area that had about a dozen random 1,2, or 3 stitches that would not allow carrying the thread to the next group. I was getting ready to cut another 'normal' length of thread - when I realized, I could just cut it to 3 or 4 inches and immediately have 6 lenghts of thread perfect size for the confetti stitches. It worked out great and I continued my stitching and found that my stitching session was less frustrating.
I thought I would share in case this could help someone else. I'm sure others have already thought of this and/or have another method that works for them.
