When you get a project professionally framed do you get glass inserted into the frame? Why or why not?
Yes, definitely! All my cross stitch pieces are professionally framed and glass is necessary in hot and humid Malaysia. Also, I have this hope that all my work will become heirloom pieces someday and that my grandchildren will want to keep them (though I'm not even married yet much less have any children but one can dream, right?) So the way I see it, the glass would not only protect the cross stitch piece from dust but whatever environment the piece end up in, be it smoking room or some place that kids with sticky fingers might easily reach, it'll always be protected.
