Framing Question

I wouldn't frame any embroidery without glass. Dust and other pollutants would quickly rot fibers. I have two Chinese embroideries (silk on silk organdy) hanging in my bathroom under glass. They are fine and have been there 4 years. Prior to that, they hung in my bedroom for 10 years. I have several other embroideries hanging under glass, all from the 1970's. They've never needed to be cleaned.

I would use the glass you have. The object is to keep it away from the embroidery. A mat or spacers will do that. Hang the finished embroidery in an area that doesn't get direct sunlight. It will last years.

That's my two cents. Lucky you. I have a lovely oval antique frame and no glass! One of these days I'm going to put something in that frame. Dianne
