About 1980's I made a few latch hook rugs here in Oz. There was a lattice backing onto which I hooked the wool, with a properly made latch hook. In all cases the pattern was out of my head. The first few were abstract patterns, but the two i am most fond of are of a wattle pattern. The were made with a thick wool, and the number of young ones who get their shoes and socks off to go bare foot on them is satisfying.
