I am sure that most of you have seen this method of creating half square triangles, but perhaps those new to quilting have not. the pictures below, I hope, show how it is done very clearly. I made enough half square triangles for a full size quilt in one long afternoon - that includes cutting, sewing, ironing and squaring up the blocks.

two squares, right sides together, sewn on all four sides

That's a good one. Pictures speak a thousands word...or how ever that saying goes ;-)

Just be careful they don't stretch since all your outside edges are on the bias.

Starching profusely will help that.

How do you determine the square sizes for the blocks that you want to make? For instance, if I needed 6 1/2 inch half square triangles, what size would the two squares need to be?

I cut 91/2 in squares and ended up with 6 1/2 in half square triangle blocks.
