Blubird - Yes, the big difference between a mushroom and a box cushion is how tight you pull the liner BEFORE you staple on the decor fabric. You will need a staple gun and a helper. Do the center of each side, then work out to the corners by adding two staples towards the corners on each of the 4 sides. Keep the number of staples per side equal and keep checking the grain to keep it straight. You can also cut a small bevel out of the edges of the foam to make the rounding a bit easier.

I am odd person out. I happen to love the leather. I think your chairs are really cute. I might consider upholstering them in a more durable soil resistant fabric even though I like your choices. I do like the greige posted above and can also see your chairs in a buttery yellow. If you really want a different look you could strip the wood and leave it nude or distress it with white wash. In the current state they do match your dining chairs. Congratulations on your find.

Me again, Tammy. Thanks for sharing all the photos of your cozy home. If you like it the way it is, just enjoy it. If you're wanting a more modern look, start two Ideabooks on Houzz, one "Transitional" and one "Modern Farmhouse." Save photos of houses you like that seem realistic with the style of your house--the "bones" of it, and what you already have. Look up something called "negative space." Here's an article on it in Houzz. It's about the nice sense of space and flow you get when your eye can rest on empty space. Not every wall has to have some little object on it. More space means you focus on a few nice pieces, an art work, some photographs, plants, etc. so your eye doesn't get too overwhelmed at taking in too many small things. That's why I suggested removing your metal shelves in the dining room to focus on your lovely hutch, whether it has a top on it or not. [https://www.houzz.com/magazine/the-power-of-negative-space-in-interior-design-stsetivw-vs~97343035 [(https://www.houzz.com/magazine/the-power-of-negative-space-in-interior-design-stsetivw-vs~97343035) Consider removing nearly all of your "signs" -- not all of them -- and other objects from walls, cabinet tops, etc. Put the stuff in a box for a while and see if your rooms seem simpler and spacious. Comments on your photos: --The bathroom is really nice--great paint choice; not too many knick knacks; nice shower curtain. --Sun porch: take off everything from the walls behind the corner wicker chair. If you want, add a little modern-ish reading light over the chair to suggest a cozy reading corner. One pillow--tops-per chair! How can you sit down otherwise? --Daybed/office room. If budget allows, a simple blue tailored print or solid cover would work better than the ornate spread on there now. Get a nice horizontal painting for over the daybed and remove the other little painting entirely and take off the metal thing. --Bedroom with brown tufted headboard. Hang the mirror and get yellow and blue curtains with coordinating yellow and blue shams and bedding. --Den with big brown couches. Move the sofas about a a half foot from the wall to add some visual space to the room. Move the the horse art to the window wall with nothing else--zero. That way, they'll be the first thing you see when you enter the room. Get a ledge shelf for the other wall and arrange JUST A FEW PIECES YOU LIKE ON IT! Negative space is a positive! Get a round tray for the ottoman in an accent color and leave it empty for people to put down drinks, food, etc. No pillows would be better than the floppy oversized ones on the couch that just look kind of sloppy. Less is more. --Fireplace room and everything that can be seen looks nice. If you have doodads hanging elsewhere in that room, take them down, so the focal point is that lovely fireplace. --The big bedroom. Move the mirror elsewhere. Center the dresser. It'll have more impact by itself. Again, doodads off the walls. Remove the little chest from the window. It's just another piece of visual clutter. You want a sense of the windows and light uninterrupted by that piece. Get some great curtains for this room and bedding that goes with them. With all the bitty things removed, these full curtains, hung very high and right to the floor, will have an impact. So will your nice bedroom furniture.

Yeah, I know it’s a tall order to come up with something that accomplishes what I want but I figured I'd see if others on Houzz had some ideas. Both sectionals that I'm considering are pretty spacious. The first one is 144” x 79” and the other is 120” x 110.” msteezzy - here’s a picture of the space you asked about.
