Here is a quilt top I've worked out, along with some pics to illustrate a few of the 'tricks' I used to make it.
I worked this variation out in two sets of colors: Dark and light green, and Purple and very light tan. You can see that my variation does not 'line up' like the one that inspired it. (https://groups.yahoo.com/neo/groups/husqvarnavikingquilters/photos/albums/1666048877/lightbox/161819480) All of my Dark green rectangles have the light green corner, all my light green rectangles have the dark green corner. Same with the other two colors- so there are four 'bricks' here-
This was constructed by cutting 5 1/2 inch wof strips. For each set of 4 20 1/2" star blocks, you will need 4 each of 16 inch strips and 6 inch strips of all 4 colors.
Mark the center line of the 5 1/2 inch square that is 1/4 inch inside the 6 inch side of the small patches.
Then I pinned all the patches and chain sewed the 1/2 squares.
Here's how I kept the patches centered while pinning.
Make sure that all your diagonal center lines travel in the same direction!!!
You need all you blocks to have the same corner- no mirror twins!!!
Then it's cut the diagonals, and press. I took care pressing those bias seams.
Then I worked from my cartoon to assemble my blocks.
Now I have the quilt top's 12 blocks to serve as my cartoon. Well, that was fun. Except for the number of times that I twisted one of the 10 1/2 inch sub-blocks the wrong way somehow, and had to rip and resew. It was a testament to making the same mistake over and over again. Apparently, I practice what I know.
