Lazy Saturday  indeed …  
You will need  2 sheet of  paper   Sheet “A” 4.25” x 11” (Inner pop up) and 
Sheet “B” 4.5” x 9.25” (Outside envelope) 
Sheet “A”  - Score at 2.5” and 4” and 5.5” and 7” 
CUT a slit  between the 2.5” and 4.1” score marks in the middle in order  to fit the  gift card—roughly  3.25”-3.5”inches in length. 
Fold the  score  lines and  glue  ONLY the  two top edges together.  You  should  end  up with it looking like  this  : 
Sheet “B” - Score lines at 1.25” and at 5.5” 
Glue Sheet “A” unto Sheet “B” just under the  1.25 score mark .  GLUE  ONLY THE  TOPS together  so that  you can insert a tag . 
Glue the  bottom of Sheet  “A” to Sheet “B”  - Press the  card  down. if you scored  at the  4" ( "sheet A" ) 
You Should  end up with this : 
FINAL SIZE IS 4" X 4.5" - WHICH TOME IS A PERFECT GIFT GIVING SIZE !
Time  to embellish and  I ended up with this  : 
ADDED A HIDDEN TAG !!!
