Personally, I won't use monofilament thread, I don't know if the thread was the reason for your problem though.

A sharp point, or Microtex needle is a good choice for invisible thread. If you are looking for a machine needle that is good for quilting with monofilament, try a 60/8 needle for best results. The sharp tip gets it into and out of fabric easily.
Always look to the needle type for the type of thread you are using.....several websites recommend the 60/8 needle for monofilament thread.

Help....I just used a mono-poly in both top and bottom threads in a quilt(comfort quilt for a child with CF) that is to be used. Is this not a good thing?? Per a suggestion from a tutorial. (to use the same thread in the top and bottom)
I bought the thread it at a LQS. "As it hides a multitude of sins" I used it for SID only. I am confused...
I did have problems with breakage until I changed to a smaller needle (75/11).

I use monofilament in the top only with a fine thread like Aurifil in the bobbin. Some machines will state in the manual do not use monofilament in the bobbin. I also use a Microtex Sharp.

The issue with monofilament thread in baby quilts is -- especially if some of the stitches are large or loose -- that the thread can get tangled around a baby's finger or toe and cut off circulation. This is why it is not recommended for baby quilts. For an older child and adults that is not really a problem, as they can either take care of it themselves or show the problem to someone who can. This is a rare problem with monofilament, but it has occurred.

This is somewhat less of a problem with SID since the stitches are likely to be even; it's more of a problem with FMQ.
For the child with CF, you may need to decide whether or not the child can show this problem to an adult. If so, I would say you are okay.

I use monofilament a lot, and I have it in both the bobbin and the top spool. Before I switched to a special "metallics/monofilament" needle I had the same problem. As for the issue of getting caught around a baby's toe or finger, make sure to double-lock the beginning and end of each stitching session and make sure that your stitches are all the length that you have selected with no loooong stitches that can be raised up.

I was taught to hand wind my bobbin with monofilament thread and that seems to work. It does take time to do it.

Are you using a metallic or topstitch needle? That plus loosing the tension a little should help.
