Step 6: WEDGES PART II
If the thing you are scanning is a book with a wide spine, you will definitely need to cut the two wedges apart. Remember to flip one around so they are facing opposite each other.
Take one wedge, and tape it to the table, first on the inside edge, and then on the back edge.
Set the book between the two wedges. Move the remaining free wedge up against the spine of your book.
Remove the book.
Tape the wedge in place.
CONGRATULATIONS! You now have a handy book cradle that makes scanning easy and consistent.
