I bought acrylic templates ( an entire package of multiple sizes) for the flying geese pattern from Hariet Hargrave ($36), the master heirloom quilter teacher and author who lives in Colorado -- and I found that working with them gives me precision. I made the smaller, very tiny size of flying geese, and it was so enjoyable to square up my rectangles with the templates. I would like to work with Marti's templates, so I am reading responses from other quilters to see if they like Marti's templates. Thanks for starting this thread.
