Congrats! I use mine all the time. Here are the ways I use it:
I try out different color/fabric combinations to preview what the quilt would look like.
I use it to estimate yardage.
I like to see if I can recreate quilts in EQ that I see online or in magazines. It's a fun challenge and hones my piecing skills!
It's very easy to take a trip to What-If Land. What if I added applique here. What if I rotated this block. What if I set the whole thing on point, etc.
