Assuming you don't own a sitch pattern book, I would go to the library and see if I could check out one or more.
Barbara Walker treasury books
Harnomy Guide to Cables
Vouge Stitchionary Vol 2-Cables
These are just a few on the market. My library doesn't have all of these, but does have a few of these plus some others.
If you can't get any from the library, I'd poor over pics of any type of knit pattern with cables on it that you can find on the web and see if any of them appeal to you and will fit in the space requirements of the fingerless mits.
Mirl56 at Ravelry, too.
Learn from the mistakes of others. You canít live long enough to make them all yourself. Eleanor Roosevelt
