I have a fairly extensive library when it comes to quilting books.
Another of my favourites is
Jinny Beyer's Quilter's Album of Blocks and Borders
I prefer to draft from scratch rather than using the design software. I feel that I understand how a block should look as well as how it goes together if I draft manually.
Jinny's book contains over 750 geometric designs and each block is sketched in black and white.
It also gives an insight into the possibilities of fussy cutting.
