The more they recognize and appreciate the possibilities, the more likely they are to recommend or specify art glass. By taking it upon yourself to help educate them, you stand first in line to get the business. This means contacting and meeting with local interior designers, showing them your portfolio and examples of other work, too. You want to impress them with the possibilities, so that they will consider art glass, in it's many varied forms, in their projects. Be prepared to be persistent.
Good designers are busy designers and their time is limited.
Make your first meeting a valuable one. If appropriate, invite the designer to bring their customers by your studio. This can be a valuable idea resource for everyone involved. Show interest in the designer's work, too. If you end up working together the relationship will be a cooperative one.
