My initial thought was to make sewn felt finger puppets--and I did find a source for a nice pattern. But then I decided to check the "Flannel Friday" boards on Pinterest, and sure enough, Library Quine, there in bonnie Scotland, had something I could use!
I went to the pattern she linked to, printed it out, cut out the pattern and with the help of some stiffened felt, an X-Acto knife, scissors and my trusty glue gun, made two crows in short order.
I only made two crows, because the way I sang this, the third crow "wasna there at'a". And when we got to that part, I opened my arms and shook my head and the kids and the parents really liked it.
Just for the heck of it, I am offering my sung version of this. I am not Scots of course, but a Jewish girl from New York City, however, we can roll our "rrrs" pretty well too, and this song wouldn't be any fun if you sang "Three crows, standing on a wall". Boring!
I used these with the leg holes, but I think I may try making legs for them and mounting them on sticks for the next time I want to use them. For use them again I will!
