Yule Pop Options

I was playing around with ideas for my Yule Pop quilt. Instead of variegated bubbles I thought it might be cool to have the bubbles/ornaments in a specific shape... a Christmas shape since this is a Christmas quilt. I thought a Christmas tree might be pretty cool. I bounced the idea off Allegory and she thought it would be best to do a little sketch to figure out how it will work so I've been doing a little sketching and coloring this morning.

The top is a guess at what the tree would look like in the colors that are present in Jovial. I removed the whites and it probably won't be quite so uniform but I was just trying to get an idea if I used white as my bubble color. When I did it, I thought it looked too much like an arrow instead of a tree so I tried some ideas on the bottom. I sketched out the blocks in a regular way (looks like an arrow), and then I sketched them with the squares alternating instead of being lined up. This looks more like a tree but my bubbles won't be lined up so now I don't know what to do. I'm not sure whether to keep trying to make the tree work, try another shape, or just do it haphazard and call it done. Think, think, think...!
