Limbania, you sound a lot like me! I have so many PHD (what a great acronym!) and things designed, fabric bought, not started yet, and then things planned but not with fabric, and then ideas.....and then more inspiration hits and there it all is and the list keeps growing. I don't stick to any kind of rule, I just work on what I feel like working on (unless there's a deadline such as for a gift, and even then it's a soft deadline). I so far don't get tired of any one project, though sometimes if it is a very monochromatic project, I get bored of the color scheme so swap over and work on something else for a bit. And also do small non-quilty things in between (ipad covers, little bags for my boys, stuff like that). Right now, I have 3 things that are in progress, 2 kits to be started at some point, and 2 more quilts planned & at least some of the fabric bought. Luckily, one of those (with all the fabric bought and probably lots of left overs) is the one for this challenge, so that will be fun. I'll post my EQ7 drawing of it later on, it's over on the other computer....
(and the list of ideas that don't have plans yet? let's not go there.....)
