I looked at a photo on the Crafty Weasel site to see what their version of a sling looked like, and it looked similar to others that I've seen. I look forward to seeing their instructions for making ferret-specific slings. In the meantime, if you want to make your own sling, you can search online for sewing instructions for Baby slings or try to find Simplicity pattern 3712. You can also look for dog slings. I designed my own version of a sling carrier about three years ago, basing it on a picture of a dog carrier that I found online. It is a bit different than the Crafty Weasel prototype, but it does the job. I use my sling when I take my ferrets to the vet. (I don't have a car and it is faster to walk to the vet's office rather than take two buses and go the long way around.) Inez [Posted in FML 6578]
