Bloc Loc 4.5 inch Square

One of my favorite tools for making accurate square-in-a-square blocks.

The Bloc Loc groove locks onto the seam allowance, making it easy to position the ruler and trim the block accurately without fighting to keep the ruler in place.

Simple tool. Much easier trimming.

WHY I LIKE IT

I reach for this ruler whenever I’m making square-in-a-square blocks. It takes the guesswork out of trimming and makes it much easier to get consistent blocks — especially when I’m making a lot of them.

It’s one of those specialty rulers that earns its place in my sewing room.
