Why?
For months and months I've quilted using the same big cone of thread and a size 12 needle. For the past 2 days, I keep having skipped stitches. I've changed out the size 12 needle, no difference. On a whim I switched to a size 14 and the skipping has virtually stopped.
Why??? I am not using a new pack or a different brand of size 12 needles. Same package as always, I bought many packs in one batch so essentially the same needles.
Same thread. Same quilting cottons.
Can tension somehow make me need a larger needle? Perhaps something changed there? What else could it be?
I've solved the problem but I need to know - why??
