Finally a tool to master one of our most loved patchwork units! Affectionately named "Peaky and Spike" by quilter Doreen Speckman, this classic unit involves three elongated triangles with sharp angles and is notoriously difficult to construct. Deb Tucker's V Block Trimmer has angles that allow for quick and easy cutting of both center and side triangles. When stitched, the resulting unit will be slightly oversized and then precisely trimmed using the guide lines on the toll. the outcome will be a perfect sized square with exact 1/4" seams on all sides and seams properly positioned for high quality end results. The V Block works with 11 different size units from 1" finished to 6" finished in whole and half inch increments.
