Sewing/Quilting Peas: Starting "New Lifetime" Project!

Have you ever done this knowing it might take you years to finish?

New project is a yoyo quilt. Yep! Will need to make around 1800 of those little buggers.

Just finished a cross-stitched sampler that was 18X24 and took 18 years. The one before that took 25years and was 25X26 inches. 

I do lots of all kinds of crafting and sewing. But it just seems like I have to have a couple of forever projects going.

Do any of you have "deliberate" long term project. My husband I am a definite optimist because I do this. LOL He asked me how long this one was going to take. I jokingly said 20 years, and he replied-"ok, I'll make a note, it's for you nursing home bed!"
