Make notes about materials, colors and styles you like. Check warranties, care instructions and necessary maintenance of materials. Be sure the furniture you choose is durable and that parts will be available when you need them. And don't forget accessories such as side tables to hold cool drinks or a baker's rack for potted plants. Wrought iron seems Victorian, but other metals lend a 1950s retro mood.
Wicker is romantic, wood feels warmly rustic and resin plastic speaks of a no-nonsense practicality.
Choose fabrics treated with water and stain repellants or treat them yourself before using. Plan to clean and retreat fabrics annually. Keep budget in mind, but shop for value over price. Flimsy materials, complicated assemblies and delivery hassles can be costly in the long run. Look for bargains in floor models, discontinued styles and pieces with minor scratches or dents at reduced prices.
