Help! Invitations and pocketfolds!

So, I had my invitations designed and using the vistaprint template for a 5x7. I ordered the samples from vp, and also had every intention of using cards and pockets for my pocketfolds. I also ordered samples from them. So, they came in the mail the other day, and when I put the two samples together guess what?!?! The invitations are too big for the pocketfolds! Apparently, vistaprints 5x7's aren't true to size! They are actually like 4.72x7.28!! What the heck am I gonna do? Any idea where I can get pocketfolds that will fit that? I had thought about just making them, but when I look at the diagrams, I get overwelmed. I need to figured it out soon b/c I need to have them mailed out in the next few weeks. I'd really rather not cut my invitations...I'm afraid you will be able to tell. Help Help Help! I know you ladies will have some insight for me..I can always count on yall!
