i don't know if she'll find fq's in africa. she may be able to get stripes good for borders and some co-ordinates. decide on the size. that will tell you yardage for the border fabric. then figure out yardage for the inside and decide how you want to break that area up. then add extra for a change of mind. colors may be very limited. earth colors are big, usually with one other color like blue or brick or poo-poo yellow. i sew for someone who brings back fabric and has clothes made from them. by the way, what she brings back is not closely woven and doesn't wear well. and it MUST be prewashed.
