Silk Flower Wall Decoration. Not for everyday, but this would be so fun near the end of winter. I'd put them on a piece of fabric to hang, or some plain white drapes instead of the walls, use safety pins, eaiser to remove than tape.
Clean Lines. Use various widths of masking tape to make the straight lines. Use four colors of paint and ONE brush. Do not wash the brush between colors. Start with the lightest color and procede to the next lightest until your canvas is covered.
