Frequently Asked Questions
- Why an exact-size charm ruler?
- Overhang is error — a bigger square hanging past a 5" charm gives the blade edge nothing to reference and the hand extra acrylic to stabilize. The 5.5" fits the unit like a lid, and precision at small scale is where quilts win or lose flatness.
- The mini-quilt connection?
- Modern minis run 5" and under — this is the squaring tool for the entire genre, where a 1/16" error is proportionally four times what it is on a 20" block.
- 5.5" or the Pink 6" square?
- Precision versus range — dedicated charm and small-unit work takes this exact fit; the 6" trades a little precision-comfort for broader coverage. Serious pre-cut quilters run both.
- The HST assembly line?
- Charm-pack HSTs are quilting's favorite quick project — this ruler squares each unit after pressing, the step that separates crisp triangles from wavy ones.
- Same QS grip?
- Full coating — and at four repositions per squared unit, the grip earns its keep here more than anywhere.
