Get a price quote from a local shop that does sew. It may end up being less than the other two options. I live in Miami but travel throughout Palm Beach County for work and I always use a little shop in Boca for all my seamstress needs like clothing repairs, changing curtain sizes, etc. I have no idea what something like this would cost but you can always call and ask for an estimate. If it's too much, you haven't lost anything. I think it is called Sew Much Fun.

Maybe you should just spice them up with pops of color using pillows and blankets. Or change what's behind and beside them to really alter the look of the whole area. Another good way to change the look is to change the lighting, which can make a world of difference, or change the wall color behind the furniture.

Thanks! I'll try the blanket and pillow trick. I might even attempt to sew pillows. Surely I can handle sewing those. Getting to a fabric store and actually figuring out what I like will be a challenge for me, but I'll give it a go. Next year I'll check out prices for someone to sew covers.
Unfortunately, lighting won't change brown to blue, which is what I want. Last year my husband and I lived in a 340 sq ft RV for 8 months, while we transitioned from our old town to the new (through the snowiest winter on record!) and EVERYTHING in the RV was brown. Thus, I now DETEST brown! Go figure we have ALL brown furniture!
