In the top photo, the marked strips are shown gathered along the marked lines. Use a long running stitch, almost 1/4 inch long. Use hand quilting thread for strength and durability, and match color to fabric. The contrasting color shown here is for photography purposes.
You can see the black and white, coin ruched 2 1/2 inch strip has been placed at the center of the finished 5 inch strip to make a Jumbo flower with the TR700 Jumbo Coin Ruching Guide. The pink blossom is made with the TR500 Large Coin Ruching Guide and the peach and multi color yellow flower are made with the TR400 Small Coin Ruching Guide.
