You will find in my Dropbox some complete sets of Funology flashcards, ready to download. All you will need to do it laminate and add magnetic tape behind them, if you choose to. It is also possible to slip them into poly pockets as a simpler option. Magnets will hold them on the board in this case.
You will find a pdf version and an editable Word version. For the sounds that do not have a colour equivalent, you can choose your own Anchor Words in agreement with your pupils OR you can adopt my choices and there are flashcards awaiting you in the downloads section of my Dropbox too.
