Product DescriptionHalf Square Triangle Ruler 4.5" x 4.5"
Bloc Loc's half square triangle rulers make the tough job of squaring up easy and fast! The groove slides along the seam to trim smaller units and allows quilters to rotate the block without lifting the ruler. The HST ruler can also be used to trim quarter square triangle and shaded nine patch units. Just think of all the projects that can be done with this ruler!
Perfect for pre-cuts and charm packs, our mid sized HST Square-Ups are super versatile! They allow you to square up smaller units with ease while being big enough for fast and unique blocks.
