I have a Triangulations CD which makes half squares and Quarter Squares. I print in on foundation piecing paper and you can do any size you want. It has a page where it tells you what size you need to make a certin finished size. It is a grid pattern. I don't use this pattern for the larger sizes as it will only do one or two per page and if you doing that large a half square it is easier to use one of the other methods listed above.
