postal packin moma, that is awsome. i hope you kept it after all that work you put into it.
love it. it is beautiful.
backings are really a matter of choice. we each do our own thing, and what is right for us.
for me, right is making the top as perfect as i can. but all my backings almost cost as much as the top, but they are all made with the very best, at least 200 count unbleached muslin that i can find. i just like the looks of it. sorta ole'timey. and i like the feel of it. it feels like a fine bedsheet. and many of my quilts are used for covers without sheets. and i hope people do their best to wear them out. and use them up. with love.
