This is the question asked by Judy of Sunshine Quilt Fame.
For me it is a different story. I get the fabric to make a specific quilt......... Occasionally I will pick up a few yards of a fabric just because I like it but mostly it is for a project. I just don't seem to have much of an understanding of how long it actually takes to make a quilt.
Being near the end of a project is also a dangerous time because I start thinking "This didn't take long so I can do it again for three special people I know."....... Then I buy the fabric for three more but before I start them I have one more thing that has a deadline and they get put aside.
I spent some time today doing a little housekeeping in the studio. That always brings home just how many projects there really are.
