u wanna have ready made sheets altered to your measured specs?
look for a local seamstress/dress maker/tailor/alteration shop...
or a tent/awning/canopy maker...
in the phone book.
almost ne1 with a sewing machine should be able to alert/fit sheets for ya.
don't 4get2 washndry then 1-2 times BEFORE alterations, to deal with shrinkage!
all of the true things that i am about to tell you are shameless lies. l.b.j.
we are here on earth to fart around. don't let anybody tell you any different. k.v.
