DIY Invite question!

especially for anyone using paperandmore products,

I am doing pocketfolds and have 4 enclosure cards. I did a dry run last night but the pocket feels a little tight and I don't even have the response envelope in there.
I printed on text weight paper and then put that onto cardstock = 1 enclosure card. Should I be doing either just cardstock or 2 text weight paper pieces? or something else?

thanks!!!
