Mereth found this pile of QAYG blocks that she never got round to putting together, so I thought I'd do a quick tutorial on the method I use. I know they can just be seamed together and the raw edges covered with a fabric strip, but I really like the end result with my method; it's very flat and the quilt has no bumps at the intersections of the seams. I first heard of this method from Queensland tutor Lyn Booth, but I do the cover strips a little differently than her.
I also like the fact that you don't lose any width in seams, as the blocks are just butted up against each other, and you get to add sashing as you go, which can save a dull set of blocks and liven them up.
Set out the blocks in whatever layout you prefer. I like to put together sets of four, and then join those sets together. On the wrong side of the two left-hand blocks sew a 2" strip that has been folded in half; use a 1/4" seam allowance. (Make sure you sew it on the edge that will be caught in the seam.)Butt the pairs blocks together and zigzag across both blocks. Use a 4.5 width, 3 long zigzag. (This is just to hold them together, the real strength of the seam comes from the binding strips that cover the raw edges.) Keep the edges of the block level at the start and finish.
On the wrong side, press the strip over the seam and sew it down, either with a straight stitch or a long, narrow zigzag. I use 1.5 wide, 2.5 long. Trim off the ends of the strip level with the blocks.
You can see that if I had matched the thread to the fabric this zigzag would be well nigh un-noticeable; as I wanted you to be able to see the stitches I used a different colour thread. I don't use a blind stitch, mainly because if you miss catching the edge of the strip there is a much bigger gap than if you miss one or two zig-zags. Also a lot of older machines don't have a nice blind stitch.
Now all the raw edges on the back are covered. On the front are two lines of stitching, either side of the zigzag seam.
Line a 2.5" strip up with the straight stitching seam, and sew it with a normal 1/4" seam. This line of stitching will be roughly 1/2" from the edge of the block.Fold the raw edge of the strip back to the seam, and press the whole lot over to cover the zig zag stitching. Using matching thread, applique the strip in place with a long, narrow zigzag. Now all the raw edges are covered!
Seam the two pairs of blocks together to make a larger unit, and continue making larger units and joining them until the quilt is the size you want. It's a very easy way to put a quilt together.
