I've finally received all the swatches I requested for the fabric for my headboard project! You can see all my options here and how well (or not well) they match the new chair:
I'm going with the bottom-most swatch which is awesome because it A) matches really well B) is super soft and C) was practically the cheapest of all the fabric I swatched! It is a velvet upholstery fabric from DIY Upholstery Supply in case you're interested. I'll be ordering 2 yards of it, which should be more than enough to cover the whole headboard and make welting. Now I'm on to pricing upholstery foam. This is going to be the most expensive part of the project so I want to make sure I really do my research on this one. Can't wait to give more updates!
