Cute patterns. I have been working on a Santa pattern from that same company for some time. Yes, I am doing the backstitch and don't really measure my length of stitch but I think just whatever you are comfortable with. I am using 2 strands of DMC thread instead of the pearl cotton. Good luck and I think you will do fine once you get a feel of it. Working on redwork is very soothing and relaxing and a great thing to work on during the evening when the TV is on for hubby. Love your idea of putting your work inside a churn dash. Please share when you finish your project.
