I'm now at the point of debating said borders. I have the main border fabric--a peace sign print. What I'm auditioning on my design wall, though, is whether or not it needs a thin inner border first. I'm thinking yes. And I'm thinking a tone-on-tone black. The border fabric has lots going on (and thankfully, wonky, so yes, it's definitely an artistic decision). Although I could probably get away with just doing the one border, I think it'll be more effective if I just do a narrow, say 1", inner border in black and then the print border. Then bind it in black again. Should keep it from spinning off into psychedelic mayhem.
I also had a last minute panic about the amount of border fabric I have. I've got half a yard, which would have been plenty were it not a directional fabric. I would end up having to blend in lots of seams and frankly, I'm just not in the mood. So I just ordered another yard. Which means I'll have lots left over. And I did second-day-air. Which means I'm paying more for shipping than the fabric. But I'm still good.
I can always make her a matching pillowcase.
