I made my very first ever quilt for my elderly dog. The teacher in class thought I was mad. My theory was that knowing it was going to the dog I didn't feel any pressure to be "perfect" and could put all my energy into learning and practising without pressure.
And it came out really well! She was an awesome old dog with massive personality.
She died last year of old age, and we had her cremated in her quilt, which was kinda cool.
