The 9 patch on the right side is 1 inch out. The orange and yellow corners should meet as they do on the left side.Hmmm.
Maybe taking out 4 of the sashing pieces was a mistake.
Or maybe I had turned one or more of the blocks the wrong way when I was sewing them together.
Bad sewing? Inconsistant seams? Poor measuring? Crooked cutting?
Not to be beaten, I sat down and unpicked a lot of the almost completed quilt top.
Back in pieces :(
At this point I was giving myself a score of E for Effort but a Fail on the project. It was hot - who makes quilts in summer anyway - I was grumpy and frustrated. Those measurements SHOULD work.
Time to call in the big guns. John entered the sacred sewing room armed with graph paper and a metal ruler and proceeded to ask numerous questions about 1/4 inch seams. Drawing on the graph paper he came up with the exact same measurements I already had. The difference was that on paper they fit, on my design wall they didn't.
Hubby to the rescue
John approached the design wall with his sturdy metal ruler. "What size is this piece supposed to be?" he demanded. "15 inches" I replied. After grumbling about having to work in inches rather than centimetres, he declared "well it's not". Stupidly, it was only this one side which was out - the other 3 were all exactly 15 inches. And stupidly it was the only corner I worked on trying to get the measurements right as it was the easiest one to reach. Sigh.
After making an adjustment and using the same measurements as before, I tried it again - Voila! Success!
