Product description What it does A precision cutting guide designed to create equilateral triangles, half triangles, and triangle shapes with consistent results. Guides your blade or pencil so each cut or mark lines up to accurate 60° angles needed for equilateral geometry. Key benefits — why you need it Accuracy: Produces consistent, repeatable triangle shapes so pieces fit together cleanly and reduce rework. Speed: Speeds up layout and cutting compared with freehand marking. Ease of use: Simple alignment and clear guiding edges make cutting straightforward for beginners and experienced users. Important attributes Function: Guides cutting and marking for full and half equilateral triangles. Compatibility: Designed to be used with typical cutting workflows and tools that accept a straightedge or guide (for example, rotary cutters, craft knives, and marking pencils when used on common cutting mats or substrates). Size and fit: Intended to work as a handheld or table guide; aligns with standard cutting and layout setups. (Refer to the product packaging or label for exact dimensions.) Material and performance: Built to provide a stable, straight guide that resists slipping during marking and cutting; engineered to produce clean, repeatable edges and maintain alignment over repeated use. Practical uses (examples) Quilting and fabric cutting: Quickly cut equilateral and halftriangle patches for quilt blocks and patchwork patterns with consistent seam allowances. Paper crafts and cardmaking: Produce precise triangular accents, envelopes, or folded elements for cards and scrapbooks. Small woodworking or tile layout: Mark repeatable 60° reference lines and triangle templates for smallscale projects and pattern layouts. How it solves common problems Eliminates guesswork and uneven angles from freehand cutting. Reduces material waste by improving firstcut accuracy. Simplifies complex layouts by giving a reliable geometric reference for repeated shapes. Quick user tips Align the guide edge with your layout lines, hold firmly or clamp if needed, then run your cutter or mark along the guide. For half triangles, place the ruler on its center guide to register the midpoint before cutting. Use with a proper cutting mat and a sharp blade for results. This ruler provides a straightforward, reliable way to produce equilateral and halftriangle shapes accurately and efficiently in a variety of craft and layout projects.
