Those are nice patterns Bez. One thing I need practice at. I do want to start one day, but I have myself spread thin now. Once I decid to retire I my have more time. Right now time is limited.

I had a lot of fun making them.

Very nice set of patterns :ThumbsUp:. I see that they have been nicely rounded, smoothed and varnished (?), very necessary to stop the sand sticking. In my experience (I have only cast once :embarassed:) a well finished pattern helps discourage flashing on the casting.
