Speaking of Split Chains

You can't imagine the delight I felt in figuring out this split chain thing.  I could do them, but I didn't like it -- and only knew one way to make it work so sometimes half my chain was front side and the other half was back side (weird looking). 
I sat down with a shuttle and a bit of left-over thread and made this string of stuff all hooked together with split chains.  Then I hunted up a couple of other shuttles with more left-over thread and made this interesting little motif.  I was disgusted to run out of thread and not be able to find the ball of thread to add more (that pink and blue stuff is here somewhere!). 
Next, I wound on two colors of Sulky and started again.  I did more rows than the first one, but it lost it's definition and started to look very cramped.  I ran out of thread then. Very likely a good thing, because I'd tatted myself into a corner, so to speak, and the rounds were not ending in good places to start a new one.
Somewhere around here is another start but with changes which have, so far, left a bit more defined negative space.  I'll post that another time.  Maybe I could actually write down a pattern instead of just going around and around where ever the shuttles feel like going.  Nah, prob'ly not.  Hmmm...but maybe that second incarnation, as a single motif, would be possible.
