Tri-Recs Rulers/Tool
 

I think it would be useful/helpful if the rulers/tool or the packaging had something on them/it saying that this is NOT a 30-60-90 or 60-60-60 ruler.

or

This tool is NOT suitable for hexagons.

I think, to the casual observer, that they might look like they could be interchangeably used - but that does not work out well.

I've always had trouble with the Tri-Recs ruler set. I cut and sewed a ton of blocks using the patches cut with the ruler and they never came out to the size they were supposed to be. I ended up using Eleanor Burns' method to create that triangle in a square block that is so cool.

I tried the Tri Recs and it worked ok, but the Deb Tucker is my favorite for TIS units. You make them a tad oversized, then trim them down. She calls it the V-block trimmer. I'm in the process of making Liz Porter's "Emily's Wedding Quilt" for our oldest niece and have used the V-block trimmer A LOT. Every unit comes out the right size with the perfect quarter inch seam allowance.

Well poo, I have this set, but I'm a beginner so I am terrible at seeing a video or tutorial and thinking "hey that will help me", I have as yet to open the package I purchased 6 months ago :o

It would be very helpful if it was properly label. It is a 57* triangle. I want one someday so I can make a storm at sea.

I was wondering WHY my Tri rec which has always been my go to ruler when making EB's 8 pointed stars. It matched the template in her book perfectly but I have had another triangle ruler that I have never used because it was different. Will have to see if that one is a perfect 60 degree ruler. How frustrating !!

I used the Tri Rec tools to make Emily's Wedding Quit and it turned great. I had no trouble using the tools suggested in the pattern.

I used the Tri-recs making my last Bonnie Hunter - worked out fine for me, she does such a great job on instructing us how to use the different rulers, if she hadn't, I'm sure I would never have used any of the specialty rulers! As you say, packaging isn't that helpful.

The whole point of this post is:

The triangle in a square unit (where the unit ends up being a SQUARE) can not be made with a 30-60-90 and 60-60-60 degree triangles.

Nor can a hexagon unit be made with triangles that make a triangle in a square unit.

At least, not if one wants the unit to lay flat.
