Cut units using Tri-Recs Tools.
Three-triangle units were nicknamed “Peaky and Spike” by quilter Doreen Speckmann who used them extensively in her quilts. The larger, central triangle is “Spike,” and the smaller, side triangle is “Peaky.” Follow our instructions for using the Tri-Recs™ tools to make cutting and piecing these units a snap.
|Cutting “Peaky and Spike” Triangles
1. Begin by cutting 1 fabric strip from each of the colors you wish to combine in a “Peaky and Spike” unit. To determine the strip size, add 1/2″ to the desired finished size of the unit. For example, for a 3″ finished size unit, cut strips 31/2″ wide.
2. Working with the strip for the center “Spike” triangle, position the Tri tool atop the strip, aligning the mark corresponding to your strip width along bottom edge of strip. Cut along both angled sides of Tri tool (Photo A).
3. Reposition Tri tool with strip width line along top edge of strip and side of tool along previously cut edge. Cut another “Spike” triangle (Photo B). Continue in this manner to cut desired number of “Spike” triangles.
4. Fold the strip for the side “Peaky” triangles in half with right sides together so you will be cutting two mirror image pieces at one time. Position the Recs tool atop the strip, aligning the mark corresponding to your strip width along bottom edge of strip. Cut on both sides of Recs tool to cut 2 “Peaky” triangles—1 right and 1 left (Photo C).
5. Reposition Recs tool with strip width line along top edge of strip. Cut 2 more side “Peaky” triangles (Photo D). Continue in this manner to cut desired number of pairs of “Peaky” triangles.
6. As you cut “Peaky” triangles, be sure to trim along the short angled line at the top of the Recs tool. This angled cut makes it easier to align pieces for sewing (Photo E).
|Assembling “Peaky and Spike” Units
1. Position right “Peaky” triangle along right side of “Spike” triangle, making sure the angle aligns with the side of the “Spike” triangle. Join pieces (Photo F). Open out “Peaky” triangle; press seam allowances toward “Peaky” triangle.
2. Add left “Peaky” triangle to adjacent side as shown (Photo G).
3. Open out “Peaky” triangle; press seam allowances toward “Peaky” triangle (Photo H).
4. Trim excess seam allowances even with sides of “Peaky and Spike” unit (Photo I).
