When you make this pattern be as accurate as possible! You need to be dead on the cutting and you must have an accurate 1/4 inch seam. Make sure your machine sews at a 1/4 inch most do not. I also recommend a 1/4 inch foot and a stack of post it notes marking the 1/4 inch on the sewing machine bed! Go slow and keep the instructions next to you. You must have the fabric guide handy as well! Have fun. This is precision piecing! Luann in CT
