I cut out a bunch of felt circles in three different sizes.
Then I sewed them all together in one long string.
[Do not be confused by pink-striped puffy thing. It's a hammer.]
I have a lot of felt.
I strung it across the dining room close to the ceiling, as one would do with crepe paper.
It turned out really nice! So colorful and fun. I'm looking forward to putting it back up for my own birthday in August, even thought there won't be a party or anything!
