Also, you will find a tutorial on the same technique that I demonstrated last night from Buttons and Butterflies. She shows several techniques to make the Half Rectangle Triangle, so be sure to scroll down to TECHNIQUE 4. I printed this one out at first to take to my sewing room with me, so I could refer to it as necessary. (But that was before I'd seen the wonderful video above!) Buttons and Butterflies is the designer of the Twizzle Quilt that I had talked about last night, and that pattern can be purchased.
Another idea a I showed you was inserting the square into the center of your diamond shape. I got this idea from Bonjour Quilts. She uses a different technique to make the diamond shapes then I showed you last night, so don't be confused by that. (she cuts the rectangles diagonally and then sews them together) Just scroll down a bit and you will see how she inserts the square into the center of the diamond shape. I think her block colors and idea for the square in the center is a fun idea. You can get lost in her blog looking at all of her wonderful ideas!
Last but not least I took a few pictures of possible layouts for the block. Hope you enjoy and are inspired to play with the diamond block a bit!
