Wooden picture frame. Take back off, paint black all over, allow to dry, simply pull doily over and put back together again. Can put glass back over if you prefer a sleeker look, this one was made for functionality to hang earrings off so opted for no glass.
Recycled alcohol bottles (ones used here are 375ml). Remove label, spray paint first colour of your choosing, place elastic bands all over (spaced and placed with as many or as little as you like) to give random stripe effect and allow to dry. Spray all over again in another colour or colour density as you like, allow to dry. Cut bands off and voila.
Remove label from jar, place doily over one side, spray paint all over. Allow to dry, remove doily, turn pattern side to wall (doesn't matter if messy as will still have great effect), place candle in holder and voila. Illuminated pattern on wall!!
