This is my daughter's Christmas card (obvious really!).  I bought the sheet from Crafts U Print and have to say I've been impressed with both CUP and the sheet.  The card size is 'large DL' which is basically A4 folded lengthways (instead of horizontally to make an A5 card).  I managed to source some envelopes that were the right size, although that took some time.  I think I will have to investigate making my own.  There are lots of smililar sized cards on CUP and I quite like them.  I did little more than make the card up (using a textured green cardstock to make the card blank) as per the instructions; I added a little bit of Stickles glitter glue on the penguins hats as you have to have sparkle for Christmas!

I'm going to print off some of the other designs I've purchased from CUP and get those made up too.
