My full caps are all French with SFS only at the hairline. I too made the mistake once of ordering SFS temples and sideburns. I usually pull the sideburns down firmly when attaching so it stretches the hairline a litlle across the forehead. But of course one of the side burns ripped doing this. I eventually cut the SFS sideburns off altogether and grafted on some French lace ones instead made from an old wig.
