I have a variety of soling sheets and unit soles for sale in my store. I will sell the soling sheets pre-cut to the size of soles in The Simple Shoemaking Handbook. Or, you can send me a custom sole pattern and I’ll cut it for you. This way, the soling sheets as used as completely as possible.
Some of the soles can be stitched to the uppers, because I am able to cut a groove on the bottom surface for the stitches to lie in. There are some types that I cannot cut a groove in, such as this Italian soling, so these soles would need to be cemented to the uppers with Barge or other shoe contact cement.
I invite you to look at the soling in my store, and email me – firstname.lastname@example.org with any soling questions you have.
