I purchased this qiviut wall hanging in Yellowknife in 1993. It used to have a tag on it with the name of the artist, as well as the community she came from, but it is lost. I would very much like to know more about the artist. Does anyone recognise the signature or the style?04 Jan 2026 17:51 +0000at://did:plc:ixie3hwiggap6rn76q32bo5i/app.bsky.feed.post/3mbmigm5njk24https://bsky.app/profile/john.dehls.net/post/3m4s3r4632c2e⏰ Deadline extended!
