Transparent grids available
Here's something to make your photo to quilt enlargement easier.
The transparent grids come in these sizes:
20x25" 25x35" 30x40"
The grids are printed on transparent plastic. You print your own photo on paper and put behind the grid of your choice.
Remember it's important to use only photos which you have copyright permission to use.
(You don't want to get into trouble.)
You will still need the book to know my methods, but these will help you to get your photomap ready.
The set of three is $14. plus shipping.
