Tent inner liner & things mountaineers use (Kendal LA9)

Would like a tent inner liner - preferable black - or some black out blinds - & those things mountaineers use to attach themselves to ropes when - ascending, descending, traversing, bouldering - whatever - for a project at my house to help stop insects % birds attacking their own shadows or fly into a window as do not see it - or think it is a rival thank you very much - Kendal Chris
