The main frame of the roundhouse would have been made of upright timbers, which were interwoven with coppiced wood - usually hazel, oak, ash or pollarded willow - to make wattle walls. This was then covered with a daub made from clay, soil, straw and animal manure that would weatherproof the house. The roof was constructed from large timbers and densely thatched. All of the domestic life would have occurred within the roundhouse.
Castell Henllys. "The Iron Age Celts' clothes might have looked like the tartan you see in Scotland and Ireland today, with checks and stripes. The Celts used berries and plants to dye the wool different colours."-BBC
Women's clothing from the swamps in the Huldremose in Denmark-unfortunately, the date is "the iron age"... (L) garment is wool, woven... "Cape" was probably lamb... (R) garment is wide "scarf" together only at the neck with a skewer from bird bones. (I see something similar to the (R) garment, made with towels, in the shower houses. )
