I need help: I have the English Garden Sampler from Teresa, and I noticed one of the stitches says "knotted clusters". Does anybody have instructions or videos on how to do these including the hemstitch that is specifically done on a cross stitch and not on "sewing" info. I'm assuming you do the hemstitch first and that's what separates them? Also once that's done, how to you start to "knot" them?? Any help would be appreciated! Thank you in advance!! Pics, videos etc.. anything!
