EASY PEASY HALF SQUARE TRIANGLES-MY FAVORITE WAYS

I love making quilt blocks and borders with HSTs, but I hate trimming them to size.
A few years ago I discovered Shortcut Sheets (no affiliation) for making lots (70) of HSTs at a time, already trimmed and ironed flat, with the dog ears removed.

Here are some of the things I've made this way-

 I usually use my ruler to check on whether the HSTs are exact.

 It takes a bit more time, but since the units are already pressed and trimmed, it's worth it. You don't need to make them all the same. By using different fabric in every other strip, you can get a scrappy look.
