I found this and am wondering if this is how they are made although how do the multi coloured rows appear, tuille doesn't come in a mixture of colours all on the same roll does it?Then I found an update of the above and it is about the same size as mine so I think we are getting close .
I think I could make those scubbies, only need 14 stitches, now where are the knitting needles, I saw them about 20 years ago lol.So obviously it wasn't me.
