2 1/2". I don't remember all the other piles she had going.
I remember when I first started organizing my scraps, they were a tangled mess too, though not as bad. I am SO glad I've kept them sorted ever since. No more ironing little scraps and all those messy threads from the fraying. Much more efficient, too.
Thanks goes to Lousia for commenting on my previous post that the dark purple flower is spinning in the opposite direction. I didn't like that block anyway, so I will replace that. It will probably be easier for me to replace the whole block, than just the purple units. The purple block will join the orphan block pile.
