When making machine embroidered quilt blocks, I always cut my background fabric an inch or two larger than the finished block. and then once the embroidery is finished, the block is trimmed to size. There is always the dilemma of having different versions of the same shape design whether it’s snowflakes or cars or hearts exactly in the center of the quilt block so that everything looks consistent when the quilt is finished.
My solution to this dilemma is to cut the basic shape using the die and taping it to the back of the ruler. I use the Creative Grids Centering Rulers and have every size of them, but if you don’t have that kind of ruler, this method is even better because you can use any ruler so long as you place your design exactly where you want it. You can fold your paper shape to find the exact center and use that to center it on a regular ruler without having to do lots of calculations around all the sides.
This is a photo of a car shape taped to the back of the 8-1/2″ Creative Grids Centering Ruler. I used the paper from the back of a shape cut with fusible, but you can use any kind of paper to tape to the back of the ruler.
