My 2 cats like to sit in my work space when I am trying to sew. We call them the supervisors. They also like to test drive any quilts I am working on. Hopefully, my grandbabies won't mind the quilts with cat hair pre-installed. :)
I once had a parakeet that had full run of the house. One of his favorite tricks was to "help" me when I was cutting out a pattern. He would follow along as I pinned the pattern to fabric. He loved to pull the pins out. Sometimes he'd play tug-of-war with scrap bits of pattern paper.
