I'll be offering 1.75 C row Control in next groupbuy, and I keep trying to get Fn as soon as GMK want to start cutting us new legends it will get done. Otherwise blank for Fn for now is always there. Or, you could get some caps from some vintage Cherry boards. If you hunt around really hard or are willing to pay dearly you can get some beige C row Control keys, and maybe something odd for your Fn key.
