Birchbark:
From: Jenny Stewart : "What matters is that you do not take it from a live tree! Even though there are more layers underneath, it's still part of the defense system, and especially if you've had as dry a year as we have here, every bit of vitality is needed. Dead trees, windfall, even someone's firewood pile can be a good source. with natural dryining the bark starts to unpeel in thick slabs. I would guess they could be soaked to aid the peeling, to soften it to be flexible & peelable. Like I say I'm just guessing based on logic, but dont be peeling it. to take scissors to strips that are already hanging would be ok. Yello birch also has a papery bark. I'd love to hear of your trials & results!" - Enna
