Muffy, if you are new to carving and your strop is already all full of gunk, you may be using too much compound. Â*It usually doesn't take much. Â*I have strops that go for months without adding any new compound. Â*When you scrape it off, try using less of it when you re-apply it. Check out this URL to the Cape Forge website that offers a tutorial on how to strop.
