Single bolt fork rack

I have a Croix de Fer Ti and want to fit small bags or panniers (I have some small Ortliebs) as low riders on the front forks but they only have one bolt, and the QR skewer (see photo). Can anyone recommend a good mount or rack that I can use. Doesn't need to be hugely strong as I am only doing soft touring and just want to put waterproofs and some warm clothes in them. Many thanks.
