Cute post. Your link is like this 'paulabquilts.blogspot.ca so when I went to it, there was nothing. I then looked up paulabquilts and was able to come to your blog.
He doesn't look guilty to me, but cat's are too aloof to be ashamed I think. Maybe he was just encouraging you to dig in and get started on yellow?
Cats show no remorse. They after all rule the household and you are at their beck and call. Now just what did he want you to do for him instead of playing with all that yellow fabric?
It seems like a lot of us have very few yellows in our stash and scraps.
That tail says, loud and clear......'just helping get you started' Pretty kitty.
That about sums up my yellow stash too! I've been trying to expand it, but it's hard to find yellows I like!
I think he is proud of what he did : )
Well, (s)he helped by showing you what you had to work with! Maybe it was a hint to get busy? ;- )
