Thanks for the link to errors.
Im having very good results with changing the methods for making the blocks. So much easier and better blocks.
The changes can be used over and over again without new figures.
Such as making 1 in by 2 inch flying geese with Eleanor Burns method for making 4 at a time and making 1 1/2 in HST either 8 or 4 at a time. It sure saves work and your pieces turn out perfect every time.
