This post is a tutorial on using
Marti Michell's Wonder Triangle ruler
to make the Triangle-In-A-Square units in
Bonnie. K. Hunter's Celtic Solstice Mystery Quilt. If you're not making
Celtic Solstice, then you'll still get some useful tips on using the
Wonder Triangles ruler, so please read on!
Bonnie designed the Celtic Solstice mystery quilt using the
Tri-Recs ruler, and she wrote her instructions assuming that ruler would be the one that people used. Those instructions still work just fine if you're instead using the Wonder Triangle ruler (W.T. from now on in this post). However, there are a couple of differences between the two rulers that you should be aware of for things to work out right.

The Triangle-In-A-Square (TIAS) unit |
The first little kink comes with Bonnie's cutting instructions. The rulers (Tri-Recs and W.T. both) come as a paired set: one ruler is for cutting the larger, center triangle (the 'triangle' part of the Triangle-In-A-Square), and the second, thinner ruler is for cutting the smaller triangle 'wings' on each side of the center triangle. Once these are all sewn together, you've made a Triangle-In-A-Square (TIAS) unit. Cute, right?
With the Tri-Recs ruler, you can cut the fabric strips for both the center and wing triangles 1/2" wider than the finished size of the unit. Since the unit we're making in Celtic Solstice will finish at 3", Bonnie tells us cut all of the strips for this clue at 3-1/2".
In the W.R. instructions, however, we are told to cut strips for the center triangle 1/2" wider than the finished size, but strips for the wing triangles should be 5/8" wider than the finished size. It wants the wing triangle strips cut wider than the center triangle strips!
DON'T WORRY!! You CAN actually use the same width strip for each of the triangles if you are using the W.T. ruler! So cut all the strips you'll need for clue #1 at 3-1/2" (per Bonnie's instructions), and I'll show you how it works out.
Take a deep breath. Everything is O.K.!
