Here is some circle letters for your scrapbooking and craft project needs. You have two sets of files A4 and 8.5 X 11. You can print them on sticker paper or on regular cardstock then use 1/2 scor tape to turn it into stickers.
Punch : 3/8 Circle. Note: on the 8.5 x 11 sheet it leaves a white border around letter which I felt gave us more options.
