And I have come to the conclusion that I prefer this type of Boom. (does that make me a bad person? LOL) With the previous boom, I tried to limit the number of seams in each block so I could iron that sucker as flat as possible for mailing. Doing everything in the flat rate envelope feels like I am not limited. I can make a block with as many seams as my imagination would like. I reserve the right to change my mind when it feels like forever before we get our squishy in the mail, but for now I am happy.
