hello i am doing a satin stitch (( the first time )) around some heart appliques (200 of them) but my problem is i found the size i wanted set all the tensions where my manual said (with in the given area) after about sewing 4 of them it seemed my feed dogs would not feed the material so i took out my bobbin cleaned off my feed dogs and all around it started sewing again got 2 more hearts done and it stopped feeding again ?? i am sewing cotton appliques on cotton material put in a new sewing needle ?? any hints as to what and why this is happening?i was thinking of re adjusting a tension but then the hearts wont match they would be looser than the other ones i did .
hopeing someone knows about this
