I'm celebrating a major birthday in October, and I would like to treat myself to some sort of quilt camp in the U.S.

Do you know of anything happening in mid-October?

Don't know if registration is still open, but Ruth over at Threads of Mine is hosting a retreat at Shipshewana, IN.

Would end of Sept work? Camp Horseshoe in St. George, WV (a whole lot closer to VA than IN is) just sent out their Fall Camp info. Camp is the 20th - 24th of September. Cost between $160 and $325 (depending on arrival day and housing option) and includes room and food. It's a wonderful place and I'm planning on going again this year - it will be my 5th time there!

ETA: oops - here's link for Camp Horseshoe: http://www.hi-y.org/CH-HeritageArts.html

eta: just saw that you said "mid-october". :-(
