Hey all!
Ive recently bought a lovely little routine from kaymar magic (soon to be closing


Its called the snap over change (not to be confused with the snap change) in which it seems 2 cards - back to back - are quickly flipped over using the thumb and forefinger.
Can any1 tell me, or give me any help at all with this sleight - magic is quite new to me and any help any1 can provide will be GREATLY appreciated.
Many thanks!
Alex
