I've been quilting since 1998 and am always learning something new - it is usually because of an OOPS! I am going to check out the Billie Lauder website and see if she has a tutotorial - but, in the meantime, I have copied and pasted the instructions posted here onto a word document and printed it out - that way I will know where to find it when I want to make some HST's.
I usually make thangles for mine, I bought a program that prints them out for me on paper piecing paper and I have used them with great success. When not using this method, I always overcut my squares, then trim after sewing. I am working on a project now that is VERY scrappy and I am using this method. I can't remember how many I need, but each block has four of them and this is going to be a king size quilt so there will be plenty to make.
