"Shabby chic decor brings in elements of romance and antiquity. Common in French cottage decorating, the shabby chic style uses light, feminine colors, such as pink and white, and employs faux finishing techniques to give furniture a weathered, shabby appearance. The DIY shabby chic paint effect looks best on wicker or on antique pieces with ornate carving. Like other faux painting techniques, shabby chic painting uses glaze to make the paint achieve different effects."
STEP 1: I suggest you use Afternoon Shower (Y4-C2-3) as your Polvin base colour. Apply 2 coats using a brush if you are painting a frame and a sponge roller for larger flat items.
STEP 2: Apply candle wax (using cheap white candles from any grocery outlet) to the raised areas of the frame to create a DIY shabby chic paint effect. Using the wax is a paint effect called wax resistance technique.
STEP 3: Mix up 60% white Polvin water based paint plus 40% acrylic scumble (use a container). Do not over-complicate the dilutions. 50% plus 50% does the trick, but from my experimenting I prefer a slightly thicker consistency. This mix must be painted over your base colour of Afternoon Shower as well as the areas you waxed.
Allow this white mix to get tacky (wait approximately 3 minutes) and then with a piece of cloth, wipe the sticky scumbled mix off. The white paint will stay in the recessed areas of the frame (provided the frame has detail).
Wherever the wax was placed the white paint will not stick and the Afternoon Shower will be revealed. Your DIY shabby chic paint effect is now complete! Experiment using a pine frame and then try out the same idea using a frame with some detail.
