I need a wee bit of advice folks.
Some weeks ago I got all of my MMBB quilt blocks out and stitched and stitched and stitched some more, piecing them together to become a quilt top. I was so excited to finally be joining all 48 of the blocks into one humungous quilt. It's so huge that I cannot even get a decent shot of it standing on my little Ikea step stool.
However, when I sewed the very last seam all the way across the middle (horizontally) I have ended up with a horrible wavy bit in the centre. It's hard to see in the pic above, maybe a wee bit easier in the cropped one below.
It's underneath the aqua points of the very large star, mostly around the green and pink 6" squares.
So, folks, how do I fix this? I couldn't really figure it out the day it happened and rather than rush in and make a bigger mess, I just folded it all up, rather disappointedly, and packed it away. I think it's probably something to do with all the bias edges involved in all the blocks stretching it all out a bit. But would it just be fixed by increasing the seams sewn on the smaller blocks? I feel that might be the way to go, although I'm going to lose a lot of the points if I do. If you are more experienced than me, what do you think? What would you do?
I'd love to resolve this and send it on for quilting, instead of it sitting as a bogeyman of a quilt in the cupboard. Suggestions welcome - though the easier the fix, the better. Anyone got a magic wand?
