The TriRecs Project; Cutting basic shapes

Welcome to the first TriRecs post – cutting basic shapes. Before I get going, I have to point out that this series of posts is a documentation of my experiments and there may very well be other possibilities.

The TriRecs tool set have two rulers: 
the Tri tool which gives an isosceles triangle (not a 60 degree triange), and the Recs tool which gives a corner triangle/half an isosceles triangle. Both of the tools can be used to make shapes from 1” to 6” finished height. The best part, in my opinion, is that you will work with strips only ½” wider than the finished size. I have used 4 ½” strips for most of my samples.

Folding the strip in half, I will start with the Recs tool to not waste fabrics. Align the 4 ½” line with the bottom edge of the strip and

the top edge with the top of the strip. 

Make a cut on both sides of the ruler.


See that little triangle sticking out under the ruler?

Chop it off; this will help you when stitching shapes together.

Now you have two corner triangles, one right and one left. Stacking strips all facing in the same direction will give you either right or left corners depending on how you flip the ruler.

Moving on to the Tri tool, align the 4 ½” line with the (here) top edge of the strip, the top of the ruler with the bottom edge, and the side with the cut edge.

Making sure that the top is positioned properly ensures easy piecing later. 

Cut along the ruler and you have this shape – the isosceles triangle. The finished width and height of the triangle will be the same - this triangle will measure 4" at the bottom and be 4" high when finished.

The third shape which can easily be cut is a Tumbler-like shape which I call a boat. Align the bottom of the ruler with the edged of the strip (or another line if you’re cutting narrower strips), and make a cut.

The boat will look something like this depending on the width of your strip and which line you choose.

There you go, the basic shapes – the corner triangle, the boat and the isosceles triangle. You can do a lot of fun with these simple shapes.

Next post: stitching shapes together.
