Borders, one or several
Butted or mitred, cut across or along the fabric. You get the strips to cut, the side and top-and-bottom lengths, the finished size and the total to buy.

Blocks set on point
Choose the block size and how many across and down. Quiltwell counts the blocks and gives the side and corner setting triangles with their cut sizes.

Half-square triangles, QSTs and flying geese
HSTs 2, 4 or 8 at a time, QSTs, and flying geese the no-waste or stitch-and-flip way. Type the finished size; read the squares to cut, how many, and the size to trim to.
