Of course, the straight stitch in running mode through layers = quilting stitch.

Detail of a new piece with the working title of “Mostly About Red”.  Green is my favourite colour though, and the next one is ‘mostly’ about greens despite the large amount of black background  :-p     The quilting thread is  a flourescent topstitching thread in one of the intense flourescent colours now available along with fabric and paint here in Uruguay.   Such things are probably nothing new in the USA, but here they are, relatively speaking – partly because the government has brought in laws requiring motorcyclists to  wear a floursecent vest for heightened visibility.  (They had to try something, as the accident rate is positively alarming)  Mostly people are wearing the proscribed vests, which are also now widely used by all kinds of workers  on or near roads and construction sites.  But I have seen these vests tied to back packs, and wrapped around an occy strap holding a load onto the back…. slightly visible from the back perhaps, but not from the front.  And now after several months in traffic the intense colour of some of them has been toned down by emission particles built up all over them – some need a good wash.  Perhaps floursecent helmets will be next ?
