Setting and re-setting your ruler can take valuable seconds, especially when you’re doing it hundreds of times. Whether you’re cutting HSTs or trimming off corners of a snowball blocks, this method lets you make a few cuts in one fell swoop.

  1. Line up (up to) four sets of blocks to trim.
  2. Lay the seam line along a gridline on your cutting mat, overlapping them.
  3. Set your ruler on top of them, adding a quarter inch from the seam.
  4. Using a sharp rotary blade, cut all four at once.

You’ll shave off a few seconds/minutes and use your precious sewing time a bit more efficiently.
