Joey is sometimes as dumb as a cow pie.
I read in the C&C thread guide to use 16 or 18 needles with the Heavy thread. Well, the thread that caused me trouble is at least that heavy and like I said I was using a 14 needle. Today I tried the same machine, with the same bobbin, and the same thread, only with a 16 needle and it worked nicely.
DUH .... where's my sign.
