I am currently preparing patterns for several quilts that require a significant number of HSTs.
Here is a document that will help you make a significant number of HSTs from yardage.
I have a few, random HSTs left over from other projects but not enough for any of these projects I am working on.
Here is the strategy I developed for creating the number of HSTs I need.
You can use these ideas to make lots of HSTs in the same color combination and/or to make scrappy HSTs.
