OK that sounded a bit silly but like the number one on top of this cake:
Can anyone help???
Or how is the number done on this crown??
You just roll a long snake of fondant as thick as you want it and form the number (if you want the curled ends, you thin out the end of the snake and coil it up). For the large topper numbers you put a skewer into the number while it's soft and left it dry. For the small number, you form it and glue it directly on the front of the item (crown, in this case) and there you go.
I'm no pro, but this is what works for me...roll out gumpaste to the thickness you want the number to be, then just shape it...roll the ends into nice little points...I always do it freehand, I guess you could print out a font you liked and use that for a guide if you wanted to...I put some wooden skewers in the bottom of the numbers so that you can stick them in the cake then. Check out my pics...the one titled "martini 21"....that's how I did the number on there....hope that helps!
I'm not an expert but the first one looks to me like it's fondant/gumpaste rolled and shaped into the number and then once it's dried placing it into the cake with a skewer for support and then gluing it with royal icing or piping gel.
The second one looks like freehand with royal icing.
