Hi there
.
Whenever I find myself stuck for ideas I do a combination of things, firstly I relax, stress certainly won't help you be creative so try to do something you find relaxing.
Relaxing for me is a nice walk through my local woodland, I always take a sketchbook as I find walking helps ease my mental block and then I have something to jot down on if ideas come.
Other things I do is read or play music and sit for a little while and usually that helps me alot.
One CD that always works to unblock me is BucketHead: Colma, it's songs are really mellow and there's no lyrics that tempt me to sing along and occupy my mind
.
Sometimes writing helps me, I'll look at fursuits that inspire me or at creatures that I find wonderfully interesting, and just by writing random little snippets sometimes ideas come from it.
I would say about 50% of my fursuit ideas come from writing random little stories of things that would make a cool fursuit.
Other than that, I make myself a nice big cup of tea, get something delicious like cake (no-one says no to cake lol) and with my tummy full and content I then get ideas pop in and problem solved
