Y-Seams

In all my years of quilting I’ve never had to sew a Y-seam! Well this assembly is going to require a combination of diamond overlap joins and Y-seams.

Assembly Started!

I did a bit of research to find out how to put this collection of diamonds together. The objective is to assemble the various hexagons where they occur (the cubes) using a Y-seam to add the third element; then joining diamonds in the usual way with the 1/4″ overlap. 

This is what I’ve managed to assemble so far. I started with the cube with the yellow dots, then added the two edge triangles, next the pair of diamonds on the left, followed by the pair of diamonds with corner triangle that creates the left corner (half the triangle will be trimmed away when the sewing is finished), and finally adding the trio of diamonds immediately above with a Y-seam.

No doubt about it – it is finicky work – I’m assuming as I do more I’ll get better, and the sewing will go faster. The trick is marking the 1/4″ seam allowance join positions before sewing so you can run a pin through the dots to secure the overlap, then stitching “from dot to dot” as various people have suggested I do. 

My 1/4″ eye is actually pretty good – I have marked some of the “dot” positions in what I’ve assembled so far, but I think I can do reasonably well by aligning a pin in the precise location I want to start sewing and finish sewing – I’ll see as I go along. The difficulty with marking dots on each diamond is that I don’t have a 60° diamond template with small holes in the corner start/stop seam allowance positions so I’m having to improvise using a ruler which is very cumbersome and time consuming.

I did print out a copy of the layout to work from – makes it much easier to keep track of where I’ve picked up blocks, how to align them, and then put them back where they belong.

This assembly is going to take a number of days because there are a lot of diamonds to put together but I’m underway.

Oh, and BTW, I cut 76 diamonds from the leftover 5 1/4″ strips (along with 45 triangles), colour sorted each pile, and put both aside. I try working on just one project at a time so I can actually finish it.
