As part of the MMQG "Challenge Yourself" Challenge I decided to use some new tools (new at least to me) plus learn to blog.
For this first week I used the Tri Recs Tool TM by Darlene Zimmerman & Joy Hoffman. This is actually a two piece tool: one for the center triangle and the other for the side pieces.
Previously my heart has always sunk when a pattern called for the isosceles triangle block. There is no easy way to rotary cut the pieces and I have always done it by paper piecing. While paper piecing makes for a perfect block, it was always a nuisance to make the paper copies and then remove the paper afterwards.
Cut the center triangle using the larger of the tools and line the bottom of the fabric with the horizontal line indicating the size of block you want unfinished. Here I want a 3 1/2 inch unfinished block so I have lined the orange fabric up with the 3 1/2 inch thick line. Rotary cut around the tool as the template.
Make the side pieces by again lining the fabric edge up to the unfinished block size, this time on the smaller tool, here 3 1/2 inches. Cut around the tool, BEING SURE to cut off the tiny nick at the side of the truncated point. This is what makes it work like a dream.
When you place the side right sides together onto the main triangle it is that tiny nick that lines up exactly with the main triangle base. It is then perfectly positioned to sew a scant 1/4 inch seam.
Reverse the tool to make the other side piece and presto a perfect block and no paper to remove.
As I am new to blogging one piece of advice I got was to include an animal in the photos, so here is our dog modelling the finished block. She feels perfection in a block should be rewarded with a tickled tummy.
To make both left and right side pieces at once you can just fold the fabric right sides together before cutting.
For the pattern I am making I need about 200 of these blocks and with this Tri Recs Tool TM it is going to be no problem. I am a convert, thanks to the MMQG challenge of trying something new. Thanks MMQG.
