The well-heeled crowd at The Fitting Room, Bea Harper's Highland Park alterations shop, was in a buying mood earlier this month. Harper hosted a reception for Shari Lidji and her Red Llama Studio's collection of custom quilts designed for dogs, cats and even human beings. Lidji took dozens of orders and sold out of every stock item she had brought with her. What makes these quilts special is their combination of wit, workmanship, personalization and good design. Lidji, who sewed her first custom quilt 10 years ago, works with the client to create a design unique to its recipient. She will even incorporate photographs or fabric from a favored article of clothing. In-stock designs start at $55, with custom doggy quilts starting at $85, baby quilts at $225 and adult quilts at $500. "Our quilts are special," Lidji says, "but not so precious that you can't throw them in the wash. Unless we're asked to use certain custom fabrics, they all launder easily."
