Cake boards (Shipley BD18)

Hi, I am looking for small cake boards, 6 inch, 7 inch, or 8 inches in diameter, or something similar. I was given a lot of China cups and saucers etc. on here to use for tombola prizes, filed with sweets etc. for a few Cat charities,. Maybe you had a small cake business and you have some left over, or even if you have any small discs from something else ? Plastic, card etc. Looking for 30+ Thanks for reading 😊
