Sometimes I can thread my machine and some times I can't. Colored thread is easier, but even then it often takes me many tries. I have tried handicap needles but they don't stay threaded. Both my machines have needle threaders on them but they have gone out of alignment and I have been told it would cost 40.00 to repair. This would be ok if it would STAY repaired but they both stopped working with in a very short time. Some times I have to wait for hours for my husband to get home and thread the machine for me. Any suggestions?
