i am near a fabric clearance center where you don't cut your own. but 2x a year they sell their stuff for $2.00 a yard. usually it's $.400. the way i figure it, the big box costs about $1.23 per yard to ship to new zealand (that's where i would be shipping). that includes the weight of the box. plus of course the cost of the fabric.
they have a lot of timeless treasures as well as the occasional red rooster, rj fabrics, etc. at the quilt show today, saturday, i saw cutesy fabric of half-naked construction workers for $9.95 that i saw two weeks ago for $4.00 reduced to $2.00. no ladies, i did not buy any. sorry.
so there is a big selection.
33 yards counts as a gift to a country where fabric is expensive. they don't know if this your sil, after all. how can they know what's a gift?
