I'm machine quilting a 50x50 quilt on my Viking; this is only the third one I've done and I've never had this problem before.
The quilt top is black, green, lime, pink, purple and orange. The back is dark mottled purple. I'm using varigated thread on top and dark purple in the bottom. There's no white anywhere. I used a thin Hobb's batting.
Problem: I quilted a grid pattern and when I look at the back of the quilt it seems like the batting is coming through with the stitches. The tension is correct, my stitches are even on top and bottom. There's no batting on the top of the quilt. It happens randomly-fine for 12-20 inches of stitching then 2-4inches where there's white (batting) showing.
Can someone tell me what's going wrong and how to prevent this please. I'm 90% done and don't want to rip it out. I can cover the white with purple marker but I want to make sure this doesn't happen again.
Thanks everyone-
Peace-Jan

I wonder if you needle has a burr on it and it is catching the batting and pulling it up through. I doesn't take much of a mark to grab on to batting

I was going to say change your needle.

I would try changing the needle too... let us know if that helped :D:D:D

Definitely change that needle. Use a quilting or a topstitch needle. And be thankful that the problem is on the back - no one need look at it!

I agree, sounds like a needle problem. At least it's not on the front so you don't need to see it. If it's for you go ahead and cover the batting with the marker.

I had that happen with poly batting but not with cotton. Must be your needle.

Thank you!! I changed the needle and finished up the quilting except for the borders. No more batting pulling through. You guys are the greatest-thanks again.

I agree with the needle being the culprit.

I had batting come through once, I changed my needle as I had just started the quilting I took it out and turned the batting over. Don't know which worked turning over the batting or changeing the needle.
