Indoor and bushcraft are two words that hardly go together.
Use a bow drill to light your fireplace maybe? or just go outside in your yard and do something.
Mostly true, but there's a lot of bushcraft prep we can do indoors.
Like... making waxed cotton balls, waxed jute, candle making....
Or.... making a leather pucker pouch to carry bannock mix...
Or... making a poncho out of a wool blanket...
Or... learning to sharpen knives...
