Moira in N.E. England

I have seen a photo of a pretty Christmas cushion made from Isosceles triangles. (2 long sides, 1 short)

Is there a trick to cutting these or will I need to buy a template?

For a pillow I'd probably make a template, for a quilt I use the Tri Recs Ruler to make life easy.
here is a demo o the ruler, https://www.youtube.com/watch?v=HQCdh-ZkRAM
and a demo of fitting them together so they come out right

and if this isn't an isosceles, sorry

Yes, that’s the triangle I’m after!

I just remembered I've also foundation paper pieced

and also if you like the technique you could english paper piece them An easy to get along with technique!

looking at your pattern the block technique shown on the first two links wouldn't work because you are not looking for a block but a series of triangles.

Thanks for your addition comments.

I have done a little EPP but don’t really fancy that for this project.

I think I might just try getting a piece of paper the size of the cushion top and draw out the design.
Even if this just gets me the size of the angles it would be a starting point.

When I’ve looked at the cushion again I realised I’ve been over-thinking this.

If I make the cushion 16” the triangles block could be 15”. (Plus an additional narrow border)

There are 5 triangles across the block. Finished width would be 3” each.

There are 4 rows so the triangles will be 3.75” high.

I should be able to draw the triangles.

Tri Rec's ruler strongly suggested.
