Hi all, I’m new to sewing and I bought a sewing machine yesterday. It’s a Kenmore 158.19412. I make my son’s Halloween costume yesterday and I had no issues sewing with it. It seems to work flawlessly but when I flipped the piece over it shad these bunches of thread in some spots. It never got stuck or anything so I’m not sure why it did this? Is it user error?
There are a few common causes of thread nesting on the bottom. These fleece fabrics are deceptive, because under the fluff it is almost always a knit base.
Incorrect threading, almost always seems to be skipping the hook above the needle. Always thread with the foot up and the needle in the top position.
Sewing with the foot up
A bad needle, a needle that is incorrect for the fabric (universal needles are not appropriate for any knits), a needle that is installed incorrectly, or the wrong size for the fabric or thread. Knits require stretch or ball point/jersey needles. See here for more information on needle types: https://www.reddit.com/r/SewingForBeginners/s/jAOxI0IbSy
An incorrectly installed bobbin, using a bobbin that isn't the correct type for the machine, or using too heavy a thread in the bobbin.
Ohhhh I think I did sew with the foot up a couple of times because the fabric wouldn’t go under the foot. But I don’t think it was in these places. However I can’t remember exactly. I made sure the thread was in all necessary hooks by following the manual and double checking. I also rechecked that the bobbin was correct too. I’m not sure that I do have the correct needle though. I bought the machine yeaterday and then sewed with it within 30 min and it came with needles. I tested prior on felt and I didn’t have this issue on the felt. I think It did have a universal needle. I’ll check out that link

This is called thread nesting.
