One of our activities during the past year has been a Bee that Kathy organized. My group made a lot of different blocks, and it was fun to stretch -- try techniques and colors that I wouldn't ordinarily choose.
Kathy was Queen Bee this month and asked for a pair of Fibonacci blocks in two contrasting solids. These were a lot of fun to make.
Participants brought a brown paper bag with scraps from one project. The bags were swapped out and each participant then had two months to make something for the owner of the scraps, adding fabric as necessary.
I drew Tamsin's scraps and, adding some Pewter Kona, made her a set of four Dresden Plate placemats. The person who had my name needed a little longer to complete her project.
The first block was a "Polaroid." We cut a six-inch square for the "picture," 1-1/2" strips for the sides and top borders and a 3" strip for the bottom border, then bordered the whole thing in a color cut at 3". What a great quilt they will make for someone!
