So, I have not read all the entries... but I picked one up at my LSS last week. They had a bunch some in for orders, and two folks had picked theirs up elsewhere, so i was able to grab one without waiting. Lucky me.
Once I found that A2 cards take 8 x8 inch paper, I was able to get rid of an entire package of 8x8 paper I have not been very wild about. So delighted to find a new use for that paper.
And today I made a 6 x6 card for a challenge, and VOILA, I was able to whip out an envelope in a matter of moments.
Love this thing! Best invention ever!
