lol...I had a lot of clear plastic storage bins and my seed cups were in those and all pretty well anchored down on tables, side by side in my fenced-in nursery area (deer). The two that blew to Kansas and back were separate on a table and I am still sick about the loss of those seeds...lol..the only seeds that I've Wintersown this year were several that definitely want some cold....Goldenrod, Clematis...and, I forget the third at the moment, may have been a Penstemon....have a whole lot of seeds to be sown, but will wait for warmer temps, been lazy this year.....
