Former Imagine Brides-? re: TYnotes...

Hi Ladies!!!
I am officially a newlywed, and promise to post review with pics soon. My question is about the dimensions of the TY note that Imagine Studios provides... with Christmas coming, I wanted to get a jump on writing the many TY's that I have to get finished, so I bought blank notecards at Michaels and was going to write them out now, and then just be able to stick them in the cards when they are finished.. so I just need to know if they are fairly standard notecard sizes or not!!
Thanks Ladies.. promise review soon!!!
