super luxury: dies for an Accuquilt cutter owner, embroidery or computerized long arm software for someone with those machines, a box of pricey thread, an extension table for their machine
less pricey: LED lights for sewing machine table; nice scissors, one of those no skid pads for their foot pedal; large acid free boxes for storing quilts, a quilt rack, some of the more expensive specialty rulers with book on how to use, a sew of Derwent Inktense color sticks for someone wanting to venture into art quilting, a hand project kit.
Not as pricey but not likely to buy for self except on whim at a show because we've learned how to live without: set of new glass head or easy grip pins, one of those table top cutters for string piecers, a fancy project bag, a sewing notion case for someone that goes to classes/retreats; decals for their machines; quilting jigsaw or book; a poster from a major show like Sisters, QuiltFest.
Wait--I think I'll use this for a Christmas wish list! LOL!
