I am getting ready to post the first block in my Mystery Quilt - it features half square triangles and I thought I'd discuss the best way to make these.
For years I followed the accepted formula of cutting the original squares 7/8 " bigger than desired finished patch.
Creative Grids even produced a really useful ruler that had its first section measuring 7/8" and then 1" intervals thereafter, it was a really useful tool, no longer available.
Then a couple of years ago I discovered Eleanor Burns TV on a Sky Channel - what a novelty getting quilting shows here in the UK. Now this lady has so many years behind her in the quilting world, it was difficult not to pick up useful tips whilst watching.................many of her methods tie in with her company's products but I found I could produce HSTs her way and square them up using my Creative Grids 6 1/2 " square ruler.
Basically, say you were making a finished patch measuring 4", you would cut your squares to 5" rather than 4 7/8", so much easier on the eyes. After drawing a diagonal line and sewing 1/4" on either side of this, the resulting patch is usually just a tad bigger than 4 1/2", and can be easily trimmed to size. I always found with the old formula that my patches were often undersized and so not perfect for matching with other patches.
I have had a search on Eleanor Burns' website and found her instructions HERE and a table of sizes to be used in conjunction with her rulers. This was found under her free patterns page and of course if you can find a local stockist it might be an idea to purchase her rulers.
I am possibly preaching to the converted - is everyone already doing this?
