Hello WMUTeach, Thank you for the comment and i hope i can explain a little.. Whoa, you have some rulers don't you :-D.. Very cool. I've decided to make my son a queen size quilt (when I get to the point of being able to and buy fabric and all. Some of is will be same colored squares and HST. As you might know the Creative Grids 4-1 triangle has 4 uses to it would be useful for more than one thing.. But I'm not totally set on buying it, I was just saying that (to someone that probably already knows..lol) I've being practicing making 6" finished HST at home away from the quilting group at church I go to, joining those together. The 6 1/2 square doesn't reach all the way across to cut mark the cutting line without moving the square.. anyway.. Again thank you for all the information you shared, look forward to more as we all go along..
