You can get an estimate by clicking on the Instant Estimate. If you wish to order, please fill out and submit the Measurement Chart to send us your dimensions. If the shape of your model does not resemble one of our measurement charts, please send us photos or a link to a web page with a description of the type of cover or bag you are interested in and we will communicate with you until we are satisfied that we can make you what you want. We will email you to let you know that your model has been added to The List of Thousands so you can order online or you can give us a call to order by phone. Once we receive your order, we always send you a confirmation letter with dimensions to double check to make sure we entered everything correctly. Measure twice – cut once!
