I've been making a lot of waves this year. I have been having so much fun cutting and sewing the trapezoids, that I just can't quit. I have 1 on the cutting mat and 1 on the design wall that I am working on, now.
I want to show you just how easy trapezoids are to cut with the House Ruler, They are accurate and there is no waste.
To cut a trapezoid, start by placing the center line of the House Ruler on the bottom of the fabric strip. Cut the 45° angle. If you have left your strip folded, you now have a right-pointing and left-pointing trapezoid. Don't worry, the ruler comes with all the instructions to make sure you get the size you want.
Rotate the ruler 180° and line the top edge of the fabric with any black line. Cut the 90° angle.
Rotate the ruler 180° again, and cut another 45° angle. Just keep rotating the ruler between 45° cuts and 90° cuts until you have cut the entire strip. Quick cutting and no waste.
Add a half square triangle and you are on your way to making your own waves.
Be sure to check out the website for the Making Waves pattern and other patterns that use the House Ruler to make adding 45° shapes to your quilts easier.
