I love a fabric problem solving challenge! I just got back from 1154 Lill Studio’s warehouse and sample sale.
They had swatches 17.5 x 17.5″ of the fabric they offer for when you go to their boutiques to make a bag. I bought 8 of the black zebra, 4 of the birds, and 8 of the black and white. Several years ago I bought two of the squares and made a vest. So I have a rough idea of how much fabric might be needed to make a larger piece.
I also bought scraps of striped brown fabric that should be enough for at least a skirt and potentially a dress. Time to get the labels off the fabric and throw it in the wash!
