You may remember my Mum's table runner that she has been working on? The pattern is called 'Plates for your Table' by Kim Walus at bitty bits & pieces. I said that we had modified Kim's instructions to suit two charm packs, instead of using fat quarters. This was followed closely by a query from a reader who 'couldn't for the life of her' work out how we had done that!
So, in case you were wondering ... Take a 5" charm:
Fold the charm square in half & press.
The dresden plate piece in Kim's table runner pattern is 3.75" long. I put a piece of tape across my ruler at 3.75" because it wasn't marked. Position the ruler as close to the unfolded edge as you can.
Cut around the wedge ruler to give you two wedges.
Open up the remaining folded piece. There should be JUST enough fabric left to cut one more wedge.
You will get one more wedge from this piece, with very little to spare!
So one 5" charm will yield 3 wedges.
This will only work for the table runner pattern. The wedges for the plate charger are bigger. We managed to cut all the dresden plate wedges and half square triangles for the table runner from two charm packs, with a few charms left over.
