Mtn, I have throw blankets in our screen porches both at home and at the beach. I don't think there are "outdoor" ones, but I just buy inexpensive cotton ones and throw them in the washer/dryer every so often. They seem to be just fine on the porch in general. Home Goods seems to always have a selection of cotton throws...maybe Overstock, too. We have some down comforter-type throws from Lands End that get used on the porch at the beach house too, when we're trying to stretch the season! We keep a stack of various throws folded in a stack in the laundry room for people to grab as needed. I also like option 2 of your pillows above especially if you want to "tone down' the overall look. Oh, I think D&A also has cotton throw blankets!

You modern furniture and tables all have hard heavy lines. Some soft greenery in planters will help but maybe for extra seating some chairs similar to these at Target. https://www.target.com/p/latigo-3pc-all-weather-wicker-outdoor-patio-chat-set-tan-threshold-153/-/A-51267971?ref=tgt_adv_XS000000&AFID=google_pla_df&CPNG=PLA_Patio+Garden+Shopping&adgroup=SC_Patio+Garden&LID=700000001170770pgs&network=g&device=t&location=9029555&gclid=EAIaIQobChMIgNi0nfTJ2QIVRmB-Ch1SpAXTEAQYASABEgJn8vD_BwE&gclsrc=aw.ds

At least some! Perhaps a blower so that the BTU's actually come into the space v. traveling up the front? Or, perhaps tell us that this is for decoration only and suggest alternatives...like the heaters we eliminated in favor of the fireplace? These heaters seem to work in an open air environment; why not a fireplace? I am obviously not a thermal expert but I appreciate your comments. Thank you.

HI Claire. If you post a picture of your place, you will get some help.
