I know there are Weaving songs, as well as the waulking/milling/fulling songs.

Which are you interested in? Where were you in Cape Breton and with whom were you singing? Was it the Highland Village in Iona? If you could be more specific we can give more information. The Waulking songs are more abundant. Weaving songs are available but not easy to find online. IF you were at the Gaelic College, where they have a weaving display, they might have sung some songs during a demonstration of weaving.

We have a group in Halifax singing the Waulking songs. The group is called An Cliath Clis

There are about 80 of the songs there. Some have translations.
