I usually keep a heavy needle on my machine as I sew alot of denim and corduroy. I didn't notice any hesitation from my machine.
Did you maybe try to sew the stick on stuff? My machine hates any stick, even the fusible lining stuff. Here is what I used...
Thanks for the compliment @marblely... Hugs
Thank you @borrowedearth. Yah maybe I used the wrong needle. Will try with the heavier needle. Oo.. My velcro had the stick on stuff at one side. Maybe that is also contributing to the problem. Thank you again @borrowedearth :)
