The quilt I am doing has a black front and a white back so of course I used thread the same but... Well see pictures.
I have changed tension up and down, changed needle, rethreaded needle and bobbin.
Has anyone else had this problem and how did you fix it?
Could it be the thread?? I am using coats and clark machine quilting thread. Its what I can afford right now.

It could be the thread(I have never used it), but I would play with the tension some more.

that's almost an impossible feat to acheive, you may have to choose one color

I had the same problem on some black borders I did. No amount of playing with tension could ever get it right for me, but I just couldn't face using the same color thread front and back.

Promise not to laugh and I'll tell you what I did to "fix it." Promise?........

I got the tension issues to the best point I could, but the little with dots still showed on the front but the black quit showing on the back. I quilted it to the best of my limited abilities and then.....................got out my fine tipped sharpie marker and colored the thread dots on the front black. Several washings later you still can't tell, so in my book it worked.

Just promise not to tell the quilt police on me.

Clever girl!

I promise. What a great Idea. :-) I am going to try that.

I have to say I have had the tension on every single number there is. I have a Brother QC1000.

AS long as the stitches look right don't mess the tension.Its just the way it is when useing two high contrasting threads.

Have you tried a machine quilting needle for your sewing machine? I was surprised at the difference.

Stitches looks fine.

Arent they suppose to meet in the middle and hide in the batting. LOL

I have been using a sharp 90/14. Didn't think about trying to change the needle other than put a new one in. I will have to look and see if I have one.
