I’d almost bet one of the first blocks you made when you were learning about quilting was a four patch. Easy to learn and easy to do in an improv way. And since I’m also about quick, I love to work in a stack and slash manner.
I like to make these blocks with each part being a different color so I usually start with four square-ish fabrics, stacked right sides up. As with other improv blocks, these can be any size.
With your rotary cutter and a ruler, make a cut across the stack, somewhere near the center, but off center. Make a second cut across the first cut, so that you have four stacks of pieces. Now you need to re-arrange the stacks by moving one piece from the first stack to the bottom of that stack, two pieces from the next stack to the bottom of that stack, 3 pieces from the top of the next stack to the bottom of that stack and you can leave stack number 4 as is.
Sew the layers together, not trying to match edges! My system for keeping things straight as I chain piece these is simple. I lay half of each block on each side of the needle.
Then I sew the top pieces (top half of the block) followed immediately by the bottom pieces from the same block. As they come off the machine each block is kept together and ready to sew the next seam, with no confusion as to which half goes with which block. You only cut the chain piecing threads between blocks and the pieces of each block stay together.
When you are trying for wonky, you are happy when your seams don’t match. But sewing them together can be a problem if you are used to precision piecing. Place them so that they overlap enough to make a seam and sew along the straight edge. You may certainly trim to make an even edge but I don’t usually bother.
When you are trying for wonky, you really don’t want to match those seams. But sometimes, just by accident, you match more perfectly than when you are trying to!
So, that’s how you do it. Trim up your blocks to size, lay them out and bam! you have a quick quilt! I have often used them as a border, too. It adds another level of interest that you don’t get with a single fabric border.
