We’ve used (and seen others use) this method for tanning hides from deer, antelope, elk, caribou, moose, racoon, bison, goat, and sheep. It’s likely that it would work with kangaroo hides, but we haven’t had a chance to try (can you help us out, Australian friends?). Wet-scrape brain tanning (the specific hide tanning method this course covers) is ideal for deer, antelope, and goat hides.
If you use it to tan the hide from a thinner-skinned animal such as sheep, you need to take extra care in the scraping steps since vigorous scraping can tear the hide.
On the other hand, if you choose to brain tan a larger, thicker hide ( like elk, bison, moose, or caribou), the scraping and softening processes will be very laborious due to the size and thickness of the hide. To help ensure your success with a larger animal, it can be a good idea to collaborate with a friend and share the hard work.
