You get to decide what to put on these coasters. Family photos, dog photos, child's artwork, business logo, specific design, you name it! Please note that your images will look slightly different once transferred onto the stone as the stone is not white, nor perfectly smooth. Bright, clear images work best. These are stone coasters and will have that rustic look. Please note that I cannot work magic on photos, if I receive low quality, that's what will be transferred to the stone. Each image will be cropped square, if not already done so. ~~~~Please submit your photos to me directly 48 hours of ordering to prevent your order from being cancelled~~~~ Set of 4, each coaster has a full 3.5" x 3.5" cork backing. Each coaster is 4" x 4". The image is transferred to travertine tile for slight absorbency. The more porous the tile is, the more absorbent it will be. Each one is handmade and unique. Tiles range in color from light to medium dark. By purchasing, you are acknowledging that these coasters are individually made by hand and in no way will be perfect due to the nature of the natural stone, each coaster will be different. They are intended to have that rustic look/feel. These tiles are not always smooth and may be rough on the top, and part of the image missing where there may be holes in the stone. I do my best to position the image where it will show best. These are not dishwasher safe and should be wiped clean with a damp cloth.
