Not sure if this is art, craft, or gardening. Pebble mosaic "carpet" is beautiful. For this pebble-mosaic patio, the author modified a classic Persian carpet design to represent the creation of the universe.
Pretty DIY lace project - A modern take on the lace curtain - try a random net base with crocheted, appliqués and cutout pieces. Great use for recycling those old and new ends or bits of lace. Reminds me of a Victorian crazy quilt idea.
