I made this kind of card a while ago after seeing it in a magazine but had lost all the measurements, (although I could of easily made up my own). While on Splitcoast Stampers I saw it again and used the measurements they gave there.
If you want good directions how to make it you should probably check out Splitcoast because I am rubbish at trying to explain things! It is really easy to make and I'm sure by just looking at my one you could make your own sizes up.
Here's what I used. 4 1/4" x 11" blue cardstock for the base (cardholder)
3 1/4" x 5" white card for insert
1 6x6 piece of patterened pape
butterfly stamp from Dovecraft
metal butterfly charm and flowers to embelish
corner rounder punch and decorative border punch
For the base score the 41/4 x 11 card at 51/2" and fold. score again at 1 1/4" and fold over (this will make the flap).
Round all corners then embelish the flap. I punched a border and used some flowers, funky thread and a metal charm.
Use thin double sided tape to stick from under the flap to the bottom of the pocket, then decorate with papers or stamping etc.
Stick down the flap after you have decorated the front of the holder so your paper can go under the flap for a neater finish.
All I done for the insert was use a strip of the same patterned paper, punched the top with the border punch and stamped another butterfly to match the holder, and rounded the corners.
I think this would be nice for invitations as they are so easy to make and can be decorated in so many different ways.
Thanks for taking the time to look today.
