In the example below I used a 12" white square paper doily (you use round etc).
I attached a 5" doily in the center as a stencil, later I added a "thank you" stamp.
In the center a heart stamp, wedding rings, flowers.....etc.............
12" (or size perferred) paper doilies
5" (or size preferred) doily for stencil
Decorative Stamp and pad
Center the "stencil" doily - a fix with a small piece of double sided tape.
I use the tape so the spray paint doesn't blow the stencil away, also if you turn the larger doily to apply a second coat the stencil will not shift.
Remove the stencil after a few minutes - and get ready to spray your next doily!
I have found the metallic paints dry faster then the "regular colors" and are easier to get an
Last - add that special something to the center......or leave the stencil off, and have a classic solid place mat.
Here are other examples.... with silver paint and purple!
