I'm a bit in over my depth here, having never completed a queen-sized quilt. But I'm making progress.
Here are the square patches, each stitched from to triangles of grey/yellow/black/white fabric.
Most of the fabric was used on the tables at my sister's wedding reception, with some filler from the fabric store in the same color range.
After I'd used up all of my fabric making blocks, I made a chart in Illustrator to work out the pattern. I counted my patches and made a simple replica of each one, grouping, copying, and pasting the right number of copies before arranging them in a simple chevron pattern.
Much easier than trying to find a wide, clean, preschooler-free space to lay everything out, believe it or not. I'm using shaded overlays to keep track of which areas I've already completed: the white shaded areas on the left are completed; the grey shaded area is stitched into short rows, waiting to be assembled to finish that section.
The blocks are coming together. Instead of long strips, I sewed the first 2/3 of the top in nine- or twelve-block sections and then sewed the sections together. The hope was that I'd keep the corners well-aligned this way, but you can tell from the photos that despite my careful ironing, trimming and sewing, there are still some "off" corners. I'm trying not to obsess over it, with limited success.
The good news is that with the prep work done, the the sewing is going quickly. The bad news is that I have no idea at all how to stitch all the layers together on something so large, and still keep the wrinkles at bay. We'll have to wait and see how that goes.
This careful measuring, ironing, trimming, etc. is very different from the way I usually work with my hands. This is more like graphic design, where I treasure rulers and rules. So it's a switch, but I'm enjoying it, I think.
Wish me luck with the finishing stages!
