TAST stitch 78 is cloud filling. TAST stands for Take A Stitch Tuesday,
a challenge at Pin Tangle.
This detail is part of my pink ornament. I stitched a grid on polka dot fabric with 2 threads of mocha floss called Six Strand Sweet Hand-dyed by Jessica Burr. For the lacing I used cotton a broder.
There are more old samples of cloud filling from other participants in the Flickr TAST group.
