This beautiful 3-dimensional butterfly cross-stitch was stitched by the same lady who did the horse in the snow cross-stitch.  I came across a photo of this framing job that I had done for her a few years ago.

The wings of the butterfly floated above the cross-stitch fabric, so a spacer was installed between the 2 mats in order to accommodate the depth of the wings and keep them from touching the glass.  Tru Vue's conservation clear glass was chosen for its 99% UV protection.
