There's one thing that's guaranteed to drive me bonkers.  Well, more bonkers than I usually am!!!
One of those things is the re-naming of perfectly fine tatting terms.  After all a ring is a ring, a chain is a chain and a split ring is a split ring etc.  BUT why do people go out of their way to confuse this old git by calling a ring on a chain a 'thrown ring'. 
For goodness sakes I know we've all wanted (and probably have) thrown a shuttle at the wall, floor etc but we don't and can't throw rings!!!  They're attached. 
I know what other people think 'thrown rings' are but to me they are simply rings on chains.  They've always been called that and that's one of the reasons I still call mine - rings on chains or RoCh.
