Font quilt panel finished; now what?

Font quilt top

I sewed all my letters together and now I have this. I like it, but I'm wondering if I should just quit now or continue and make it into something larger.

This size is not particularly large and I have historically made a case against wall hangings (no function!). But I also used spray paint to make the blocks and I'm worried that making it for a bed might result in the spray paint peeling off after many washes. So maybe this should be a wall hanging (I hate to admit this).

I will think on it more, but at the present, I am pleased with the results.
