I need some help today please!!!
What do you call the technique for making HST when you sew 2 square blocks right side together 1/4" from the outer edge then criss cross x cut corner to corner to make 4 HST?
And does anyone have a link that defines what size blocks give what size HST's?
Thanks in advance!

What you describe will give you four quarter square triangles (QST) - with all bias edges!! The formula for sizes is usually add 7/8 inch to the desired finished block size for a HST and 1 1/4 inch for a QST. Personally, I always add 1 inch for a HST and 1 1/2 for a QST and then square them up to correct size after sewing. Do a Google search for HSTs and/or QSTs and you will find several links with instructions. The best way to get QSTs with straight of grain edges is to sew HSTs first, pair them up and sew in the opposite diagonal.

I believe the formula for doing it by sewing all four sides & then diagonally cutting is to multiply the desired finished size by 1.64 - 3 inch finished multiplied by 1.64 equals 4.92. Again round up (two 5 inch squares) and them trim to proper size after sewing. I don't know if there is any particular name for the method.

That is an interesting way to make 1/2 square triangles! I prefer to use squares placed on right sides together, then mark a diagonal line, then sew 1/4 inch on each side of the line. Cut on the line.

I'd go to the dentist every day of the year before using the bias edged HST. The on grain edge block is so easy to do, I seen no reason to make life difficult.
