Sorry, it wouldn't let me post pics. Current dining room (will take more pics) and a few loose ideas.

Mirror similar to mine

How about something like this? https://www.chrislovesjulia.com/the-dining-room-wallpaper/

I don't think I'd put a round table in that space. The rectangular one is fine, and I love your side chairs, particularly in a Craftsman bungalow.

I'd focus on the wallpaper, with a painted wainscot below. All the William Morris patterns are making a comeback. They're so beautiful and come in a lot of different colorways. Here are a few WM patterns for inspiration:

The second pattern, Strawberry Thief, is my favorite! And there are a zillion other patterns available. Check them out.

I think I'd do the William Morris style wallpaper and then decide about the table and chairs. Maybe keep the furniture and splurge on a new light and wallpaper.

RTHawk-yes, I love that wallpaper in Julia's home! I have some saved that are similar but didn't want to overload with too many choices.

Sabrina- I do love Strawberry Thief and actually have that pattern on my pillows. And I do also love the arm chairs, the inlay os beautiful BUT the table just does not fit the space. If the end chairs are pulled up to the table there is no room to walk behind. I feel like a circle or even oval table would allow for more space to move around. And while I do love the look of the table, it is a family heirloom and my husband insists on using a protrctive covering and >'d prefer a table thay's npt too precious.

Sorry, I missed that the room was roughly square. It looked more rectangular in your photos. I think a 60" round might be too large for that space; at most I'd do a 54" that you can expand when you have more people over for dinner.

I agree 60" is too big you need 36" all arond the table so 10'6" is quite tight both function and looks wise. You could do a 54" and if it has a lef you could push it for bigger group just be aware it will be tight . IMO I would do a bit more modern wallpaper your young do you really want gramma's wall paper . I think the wall paper is great place to add a bit of modern .IMO just because a house is craftsman does not need to be that on the interior.With a round table I would choose the ronded back chair but we need to see the table maybe a nice colored chair with the color taken from the wallpaper .

You can tape the floor or use boxes (for a 3d feel) to see difference between a 60-in and 56-in table. You can see below a 56-in does feel a bit more comfy.

Ok good point. I will look for something around that size point (hoepfully with an extendable leaf). And yes we are young-ish but I actually prefer the look of traditional wallpaper over modern. It doesn't have to be too old fashioned but I am a sucker for more botanical prints but also like stripes, gingham, etc too.
