I have discovered that the main body of the pincushion is 6 1/2 inches wide, the width of my ruler, so that was easy! and I have created a lip on the 2 1/2inch wide measurement to make it easier to butt up against the fabric by using a couple of layers of double sided tape. This is a good way of using up small precious pieces of fabric. The filling is polyester fiberfill from washed second hand pillows that were not suitable for toy filling because it was too coarse and firm but great for these. This is what I will be making during the day and in the evening stuffing them.
I will be starting on the next Aussie Hero quilt on Monday.
