Help me get the wonk out of this fabric
I am going to make a fractured quilt. To do it, I need 4 identical fabric motifs, in my case I'm using a panel. Similar to a stack-and-whack or an OBW, the fabric design has to match (ie large blue flower in exactly the same place on all 4 pieces of fabric when laid on top of each other).
My problem is that the panels are ALL wonky. They're square at the top, but around the middle they all start veering off toward the right. There is no way I could cut strips out of them and match the strips.
The fabric is pre-washed & dried. I then starched it and ironed it (I ironed lengthwise with the selvage only).
I tried stretching them on the bias to get them back into shape and an hour later they're wonky again.
I tried to match sections and put a single stitch in that section and tying it, but I'm getting great big puckers everywhere.
Any suggestions??
