Many people suggested I cross hatch it by straight line quilting in the other direction. That had never ever occurred to me but the thought of having to do that on my domestic machine was daunting. And I don't have the right rulers to be able to it on Lola.
Other suggestions were to repair the straight lines that were pulling and then be done with it. Let them love it and enjoy it as it was originally designed. That made me a little itchy because it meant the problem would continue.
Others suggested that I quilt over it on my long arm and then leave in the original stitching. I so wish I had the ability to do that. But the old stitching would make me nuts.
I quilted it on a Wednesday and it was in the washer Sunday afternoon with all the old stitching taken out. There were memory lines from the straight line quilting but I washed it again two weeks later and it's almost gone. Taking out the stitches was relatively easy and a great project for the evening and was a great excuse NOT to be working on a Lollypop appliqué block.
We head to Toronto next week and I'm happy to be returning the quilt within 3 months of bringing it home. Hopefully it has a number of good years left in it and can provide hours more cuddle time (or tent time for a 3 year old). In the meantime, you all are an incredible source of knowledge and ideas. Thanks to everyone that took the time to suggest a solution and give me something to think about.
I hope you are finding easy and right solutions for any problems you may be having!
