I would love to participate in a speed scrap! They sound so fun!
Some weekends we have morning activities and sometimes evening activiites, so I couldn't say which would be better. But I would definitely join the scrap whenever my schedule allows!
Maybe alternate the speed scrap to be in the morning one time and the evening the next time? That way people who have a set schedule wouldn't alllways miss it? But maybe that makes it more confusing?
However it works out, I will particpate as often as I can!
