Years ago I purchased this doormat from the now defunct Martha Stewart Living catalog. When the catalog was closing, I bought one more on sale and later on regretted not buying a few more. They said the pattern was based on a sea cucumber.  I've always wanted two more for other entryways to our house and finally found something so very close to the original!

Not exact but close enough!    Have you even been looking for something and then finally find it years later?
