I love this idea! You can always turn it into a lap quilt later.
I would keep the panel as is and just launder regularly to stay ahead of the mould.
Sounds like you need a better fan in your bathroom! I’m guessing you’re dusting it out regularly? Pop the screen off and vacuum out the fan too - that should help. I’m also thinking of a small battery operated fan that you can leaving running all winter to keep the moisture moving rather than settling. That’s all I’ve got for unsolicited suggestions. Tracy
What a fun idea, I would never have thought of that! It definitely brings more character to your bathroom. I’d say go for it UNLESS the fabric is really precious to you. It would be sad to ruin a special fabric with the potential mould.
Thanks @TracyMc! I do have a dehumidifier fan that sits on my bathroom counter and I washed my walls with a borax solution that seems to help.
I did take the fan apart and clean it to check it was working but I should add dusting to the regular cleaning schedule.
Unfortunately it’s not the best built apartment and my landlord is in denial of the problems in the building. So I do the best I can.
You can spray the fabric, and anything else in the bathroom, with a solution of Oil of Cloves. This kills the mold spores. The ratio is 1 litre of warm water to 1/4 teaspoon of Oil of Cloves.
