As a past quilt shop owner I wish you the best in starting your business. All the things listed above are very good things to consider in starting a quilt shop business but there are a couple more that I feel are very important. The location of your store is very important and the attractiveness of the business or building is important. Samples are important and they need to be made out of fabric you carry. Many people like to buy exactly what is in the sample so kits work well. If making kits I would only make 2 or 3 at a time and if they sell then you can make more. Classes are important and customer service is important. Many people come in to look and many come to buy. You need to let them fee like it is ok to just look. I wish you the best in your business and if there are any questions you want to ask me pm me and I will try and answer them.
