I assembled the Booga bag and used it last night when we went to a party.
Pattern: Booga Bag from Black Sheep Bags
Yarn: Noro Kureyon and Cascade 220
Needles: US 10 1/2
Modifications: I knit the bottom and a few rounds with the Cascade, which made the bottom more felty and less fuzzy.
This is such an easy project and the results so great that I highly recommend it, especially for first-time felters.
