Frequently Asked Questions

Why do mitered corners defeat so many quilters?

The angle math compounds — each corner needs an accurate 45 marked from the right reference point, and a degree of error at four corners makes borders that won't lie flat. The template removes the marking step entirely; the angle is built into the acrylic.

Mitered versus butted corners — when does it matter?

Butted corners are structurally fine; miters are the refined finish — striped and directional border fabrics almost require them (the print turns the corner), and traditional and décor styles read unfinished without them.

Beyond quilt borders?

Everything with a framed edge — placemats, table runners, quilted mats — the home-décor genre runs on box corners and this template batch-produces them identically.

Beginner fit?

The template's real audience — it converts the technique's hardest step into positioning, which makes mitered borders a first-year skill instead of a someday one.

Longarm-studio relevance?

Pre-quilting prep — studios that piece client borders or teach border classes keep it at the cutting table beside the QS rulers.
