Triangles and diamonds

Following on from our Tumbling Stars class we thought we’d show you a few photos explaining cutting 60 degree angles to get triangles and diamonds and then how to match those shapes to stitch them together.

So to begin with cutting a triangle. First cut a strip the height of the triangle. Find the 60 degree line on the ruler, line it up with one raw edge of the strip and cut your first angle. Turn the ruler around, line up the 60 degree line with one of the raw edges of the strip (it is at the bottom in this photo) and cut from (or to) the point of the triangle. Cut your way along the strip to make lots of triangles. As it is a symmetrical shape you can leave the strip folded and cut 2 or even 4 triangles at a time.

Cutting a diamond is very similar. Cut a strip the width of the diamond and make your first 60 degree angle cut in exactly the same way as for the triangle. Then measure the required length of the diamond along the strip and mark it lightly with a pencil. You can mark the length of the strip, or as many diamonds as you want to cut. And, again, its a symmetrical shape – you can leave the strip folded and cut multiples at once.

Once everything is marked, find the 60 degree line on the ruler, line it up with a raw edge on the strip and cut to each mark, keeping the ruler facing the same way this time – just slide it along the strip.

To stitch them together into rows, as we were for the Tumbling Stars block, you need to match the tip of the diamond and the tip of the triangle, leaving the seam allowances of the triangles showing half way down the diamond.

Then stitch a quarter inch seam along the appropriate side (this is the slightly tricky bit as they have a habit of turning round in your hand). The seam should end where the diamond and triangle intersect.

Finally, press the seam to one side and trim off the ‘ears’. The triangle and diamond should line up ready to be stitched to the next row.

Try this block

We’ve both been doing our fair share of chopping up fabric and stitching it back together again over the past couple of weeks.  So much so that during the course of one of our high level conferences at C&B HQ

another conference

we decided we would try a Not Block of the Month which would give us yet another reason to chop up even more fabric and stitch it back together.  Fuelled by further caffeine here’s our first offering, the State House block.  It really isn’t meant to be a Block of the Month, more of a Try This Block you might like it.  There is no further agenda, just the free downloadable instructions here.  Our other starting point was Barbara’s collection of vintage black and white blocks -here’s the original for your reference –

vintage black & white

Barbara picked up some Moda fabrics that had been lying around hopefully on her cutting table since before Christmas and in a very short time had put the block together –

making half square triangles

arranging units

putting small units together

units - correct arrangement

but it’s always fun to investigate the possibilities before committing to the “proper” arrangement …


or this?

final block

– although looking at this last pic she wishes she’d slowed down a bit and made a better job of that 4patch unit!  Oops!!  (Probably had the music turned up too loud again – Chris)

So, it isn’t a competition or a sewalong and there’s no pressure, deadlines or any of that guilt-inducing stuff, just a simple versatile block – if you decide to make your own version do share it with us.
