Join Diamond Motifs Together

Join Diamonds tog: Cut a strand of B 94" [234 cm] long. Sew Motifs together, using a whip stitch along with back loops starting at a midpoint corner from one side and jumping over to the center point to attach the other two triangles across at the same time. This will help pull in the center points to have a beautiful, closed look in the centre.

Join Triangles to Diamonds

Join Triangles to Diamonds: Cut a strand of B 36" [92 cm] long. Following the Diagram, sew Triangles to Diamonds using a whip stitch along with back loops, starting at the midpoint corner and going outward to the sharp point corner. Start again at the same point, working down the opposite side of the triangle.

With B, cut a 36" [92 cm] strand. Sew starting with the back loops using a whip stitch at the midpoint corner, going outward to the sharp point corner. Start again at the same point, working down the opposite side of the triangle. If a triangle is already in place, be sure to sew around the points of the triangle you are putting in and the one already in place to pull the points together.

Pin or block work to measurements. Cover with a damp cloth, leaving the cloth to dry.

Introduction

Hint

Pathways and Gardens are the hints for this. Smell the flowers, follow along the established pathways. There are no flowers to sew on but that doesn't mean you won't see flowers. There isn't anything in our video or pattern collection that looks like this. I pushed and did the math to make it work!

Finally, the name of the blanket was affectionately named by Jeanne. I was doing a lot of math trying to get the corners not to pucker! It's like the geometry wasn't working. In the end, the geometry was solved. Therefore a lesson in geometry!
