Cathedral window cushion
I'm going to be rubbish here, and I won't write my own tutorial. Rather, I'll link to some people who have written very good ones: click here for PatchworkDelights, and click here for Hyena in Petticoats.
I have a few things to say about sizing the blocks. I wanted about a 20" cushion cover, with 4 windows to stretch across each side. I wanted to get a good number of fabrics in there, and my lovely mother-in-law (hello there!) helped me choose the right size.
Using the magic of maths (20/4, wow), that means each coloured diamond is 5" tip-to-tip (measurement X on the picture below).
quilter's square, a rotary cutter and a self-healing mat. I'm linking to Jaycotts when I can because they've got a really good selection of tools, in my opinion!
To help press those 1/4" seams in, I made a 10"x10" card template. I could then just fold the fabric around this, press with an iron, then remove the card. Hyena in Petticoats has a good description of this method.
Each intersection of coloured windows (where the 4 corners touch) is the centre of a cream square, so I used 16 cream squares of fabric.
The coloured windows are made from squares which have side Y when the edges have been folded in by 1/4". The magic of trig tells us that Y = X/sqroot(2), or approximately Y = X/1.41. Again, you need to add 1/2" when you cut out, so you can fold the edges in later. I cut out squares of 4"x4", and folded them round a card template of 3.5"x3.5". This cushion used 24 whole coloured squares, and 12 partial squares (missing a corner) for the edges. The edge windows ended up with unfinished coloured bits sticking out, but they are taken care of when you attach the pillow back.
I top-stitched the curved folds because I am lazy and I don't trust my hand stitching to stand the rigours of my sofa.
I made the back from upholstery weight fabric to try and match the weight of the thick patchwork front. When I sewed the two together, I stitched as close as possible to the edge of the patchwork piece, as there is no seam allowance on the front as such. For a tutorial on the cushion back, clicky clicky!
