I made a quilt for my nieces wedding in Sept. and I used Minky on the back. I'm having a friend from our quilt group do the LAQ. I stopped over to her house to see how it was going and am a little upset. She is using light purple thread on the light purple fabric, which is what I wanted. But it looks like a darker color. When I asked about it she said the Minky threads have popped though from the back side. I have had 3 other quilts ( different LAQ) done with minky on the back and this has never happened. She said when it's washed it should be fine. First I didn't plan on washing it first and what if it isn't ok? Has anyone ever had this happen and was it ok after washing? Help!
