I first made abstract pieces, some of which are meant to be hung and looked at, and some used as hot-pots.
After a while I started making tree pieces (being big on texture, I really liked adding the rocks at the bottom, for an extra dimension).
As a present for a friend's wedding, I made a tree mosaic with an inset quilt. It was quite a challenge to keep the quilt (which I wrapped/glued around a smaller tile before inserting in the middle of the larger mosaic) from getting wet while I grouted the piece, and I'm not sure I'll be trying this again soon!
And, finally, in keeping with the theme of combing tiling with other media, I inserted a plaque (photo of my 3-year old nephew Jaxon) in the middle of a tile mosaic. Much easier combining laquered wood and tile, than quilted fabrics and tile!
