For the twist you have to join the regular swap first with at least 2 baggies. Then for the twist you can join and do how many baggies you desire up to the max. The twist is usually a certain thing. Like for the the next swap twist is about girls. So you will put only girl fabric for the twist. I am doing 10 - 5 inch blocks in each baggie up to 10 sets i believe. You will not use any fabric in the twist baggies for the regular swap and vice versa. You can have 10 of the same fabric in each baggie or 10 different. But as long as there is only 10 of the same fabric all together.
