Linda, that is a much better photo. I can see each individual offset in this photo. It should be easy to gentle reach your fingers behind the offset making room for a sharp thin knife to reach the stolons. I can easily see one of the stolons in the photo. Start with that one. I bet all of those are rooted as they look to be laying on the soil. Here is a photo of the one that is going to Terri this week.
You will know right away when you start to lift up on it if it is rooted yet. Don't cut the stolon until you know it has roots. Some of mine couldn't reach the soil so hadn't rooted yet. I left them attached until the make roots.
