I've never grown wooly thyme. I don't see how you can grow anything with small seed on sheet mulch. Maybe dig through it every few feet and pull it away from the hole? Just let it creep from there.
If it's not too late in the year where you live, you could plant melons. You could still plants some cucumbers here.
If the mulch is thick, you could grow vines and vegetables next year while it's breaking down enough for the thyme.
I hope this doesn't seem too negative. I know it's not what you had in mind. I could be wrong. I have never grown it. I like the idea of a thyme yard. I'm starting to turn a side yard into all herbs and ground covers. So far I've got Musk strawberries, two kinds of mint, and tiger lilies. I've got a lingonberry, but it's not doing good. I may try some thyme.
