USING MONEY instead of a magic wand, you can conjure up almost anything you can imagine, made just for you.

Today, with the rise of the community of craftsworkers, and the influence of patrons of the crafts, more people are realizing that they don't have to buy off the rack. It is perfectly possible to hunt up a craftsman and say "I want it red, 9 x 12 feet, with doodads on top." And so, after a suitable wait for inspiration and aging, it will be delivered unto you.

Rosalynn Carter and Joan Mondale have in the past year commissioned tea and tableware ceramic services, among other patronage of the arts. Many others, in their wake, are making buying a creative experience, by working with craftspeople to produce a three-dimensional object out of their heart's desire.

Some 400 American craftsmen, one of the biggest assemblages of talent this year, will offer their works this week at the Baltimore Winter Crafts Market, sponsored by the American Crafts Council. Room settings will show how crafts can fit into contemporary homes. Craft treasures from the Museum of Contemporary Crafts will be displayed in the Morris. A Mechanic Theater.

The market, at the Baltimore Civic Center (in the block bounded by Howard and Lombard Streets, Hopkins Place and Baltimore Street will be open 10 a.m. to 6 p.m. Friday, Saturday and Sunday. Tickets ($2) at the door. A preview 7 to 10 p.m. Thursday will benefit the Center Stage and the Baltimore Museum of Art (Call Center Stage for tickets.)
