For those who don't do miniatures you can use the leftovers for other blocks or for a crazy crumb method etc. They can be used to make a strip border also.
When you are using larger blocks you will have larger leftovers. The larger the leftover the easier it is to reuse.
Tomarrow I will post a mini lesson on an alternative way to piece the block with less scrap left if you are using a large template. I'd do it now but I don't have the pics done yet.
