I found it hard this time to think of variations with this stitch for myself . Except for the curvy line at the top where I was thinking a line in basic chain is obvious, but how could a line be done with separate stitches? And then I tried flowers, using the stitch both ways round, and one with long tie stitches. Also the textural 'jumble' of different threads. Then some couching. Also Sharon's padded flower. Then I resorted to Google and came across Velvet Stitch and an interesting sampler of detached chain, from which I have copied some ideas.
I still want to try some of the variations of chain stitch done as detached stitches e.g. twisted chain etc.
And if anyone please could give me advice on how best to work a 'jumble' of stitches? I found it more baffling than I expected, and I'm usually not bad at random!
