Have been following the discussion about half-square triangles -

Some of us just cut the squares slightly bigger and then trim them down after sewing.

Now with the quarter squar triangles -

The traditional wisdom is to add 1 1/4 inches to a square and then to cut it diagonally both ways.

Now I'm wondering if I would have slightly better luck if I cut my original square 1 1/2 inches larger, and then trim the finished square down after sewing and pressing.

The "scant" quarter inch thing doesn't seem to work very well for me...

(I guess I could just go and try it and see if it works, huh?)

I don't know if this works for what you are doing but thought I would put in my two cents.

Have you seen my Boston Block directions? Check out my free tutorial for making bookmarks. It is directions to making a block with quarter squares in it. You don't have to make the bookmark just look at the directions

You can make the boston block any size with whatever size template you need.
Steps - cut three swatches / sew med and light together / trim straight edge /add third swatch /cut a square out of the middle /and you have your three fabrics( quarter squares included) all sewn together before you cut.

If you buy Quilt in a Day triangle square up ruler (at Joanns with a coupon) you get instructions for both HST and QTS for all sizes up to 6 1/2 inches.
This is a very easy method.

I will try to download the instructions from Quilt in a Day triangle square up ruler.
It did not work.
The instructions are for making both HST and quarter sq triangles.
With a coupon from Joanns this ruler is very reasonable and very useful.
Gives all sizes up to 6 1/2 inches.
