Oops- forgot to write something on this post- After I cut the cardstock for the flip card I had all these pieces of 8 1/2x 3 1/2 cardstock. So I folded it 3 1/2 from one end and a smidgen less than an inch (as I recall) to make a 3x3 post-it note holder.
Take a 3x3 white CS, stamp an image (I used this one because I had it out for the other project anyway), wrap the bakers twine and tape it down. Staple the bottom and I took some post it notes, peeled off a little stack and just stuck it in the inside. Easiest hostess gift ever- all out of CS that I had cut to order anyway.
