complex stitches made up of smaller parts. Try sewing a decorative stitch withe the zigzag machine, then further embellishing with hand embroidery. I may have to try this some daywhen I get really adventurous-hope I can learn to do these stitches.
Not with concrete, but maybe clay? Get the children involved with these cement stepping stones! All you need is some cereal boxes and quick drying cement. Decorate with glass stones. Excellent idea for the kids to get their garden creativity flowing!
