Has anyone ever made a fireplace blanket?

this is my fav..... https://www.youtube.com/watch?v=UlTnjWmTfHE if you don't have metal edges, I would make a 1x 1/2" wooden frame the size of the opening so you can slide that into the firebox to hold in place, then glue and fasten to the back of your faux wood stack screen

I didn't make a blanket. My husband purchased Styrofoam insulation that he cut down to fit snug, I covered in black fabric held fabric with pins and shoved into place. Worked great.

Yes, it seems like a blanket of some kind would help and Sharon's idea is great, but I have to ask - Do you not have a damper? That is the purpose of the damper. To keep out cold and keep in the heat. A damper is located right above the firebox and there should be a handle of some sort to open and close it. Open it when you're using the fireplace and close it when the fire is completely out. Remember the same is true if you use a blanket. Don't put it back until the fire is completely out. Wishing you the best.

Is there a damper in your fireplace? That should be shut if you aren't building fires.

No, but when not in use,we use to close the damper. Every fireplace should have one. Look inside the fireplace and pull the handle to close the open vent. Be sure to open it though if and when you start a fire!

I guess you have no damper? I've used your idea in a stairwell in an old house without central heating and that worked well. I'd make a frame out of 2x4s, extend feet out on one side. Upholster and make it a bit puffy on the back side to work as a gasket. Beware of the danger of fire, which would be high risk.

No really want someone who has made a blanket for the fireplace. Damper is closed but cold air can still be felt. Saw a blanket in Plow and Hearth but of course a homemade one would be so much more special. Just didn't know and hoping someone does like what it should be made of and what kind of magnets to use etc. Even thinking if it was quilted it could look like a fire. Still hoping someone else might answer this.

It sounds like you have the idea you want to execute. Find the picture and copy it.

I'd get fleece material in black - for the background, orange and yellow for the flames and maybe some brown for the logs. Then I'd make a full size pattern on paper so you know what it'll look like and can make changes before cutting the material. You can stuff the pieces with batting to make them 3-D. Cut and sew.. Magnets come in all sizes and strengths. If your fireplace has a metal screen, buy a single magnet and try it out. It may not hold magnets.
