Jitterbug

Recently, I was looking at blogs that had free motion quilting on batiks. I cannot remember where it was that brought this up and is now causing me to ask those of you here. The person domestic machine quilts and stated that batiks create problems with the needles/thread in FMQ with thread breaking, needles breaking and such due to density of the fiber. She stated she used a top stitch needle(# 80 I think or something like that). I looked on other googled sites to see about this. Some said that they switched to sharp needles,but it caused micro tears in fabric, some continued with round end needles, with certain thread weights,ect. Anyway, I knew from being a hand quilter that I would wait on using my collected batiks due to the density of the fibers for when I learned FMQ. I have been working at FMQ with my Juki and I am getting better at it. I am going to cutting a pattern in another month to use my batiks.It never entered my head about the issues that could arise due to using batks on domestic machine quilting when I knew from it and hand quilting.

I tried to find answers here on the board using the search as I always do,but nothing connected to my worried and confused thoughts about this. I know I see so many wonderful domestic machine quilters here displaying their work on batiks, so I thought maybe you guys could offer your thoughts, tips and the way you go about needles(types,numbers) thread type and weight ect. OR if you even had this type of problem? Thanks and I look forward to reading your opinions and experiences.
