I get my Susybee panels from my friends ebay store, dandylion fabric. I don't know if I am allowed to post a link, I'll add it but if it is not allowed, please remove it but not me lol. This is a playmat, not panel, but there is a panel available. I did this free motion on an innova longarm, sorry I'm new to quilting and don't know what a DSM is. Have a great day
