The crochet Moebious I made was Calculated by me, without any help and before a nice Belgian lady Ria taught me the knitted `no seam` version.
In fact I have been exposed to `Paper moebiouses`,but only when I read Elizabeth Zimmermann`s "Knitting Around" , School
House Press, 1997 [4th press] . Did I see any suggestion to use it as a Shawl . I liked the idea in general, but was not so keen on the
false seam, After looking at a paper version and thnking about the concept, I was sure that One should be able to make it in one piece,from the center out. I discussed it with my Friend the mathematician and my son who studied math, and played with possibble `turning` points. I realized that when one starts with a basic chain it is not so easy to turn it so decided to start with a Basic Double crochet row [Dc usa term=treble uk term]
Cast on: 3 st , make 1 Dc in the first st, make next dc
in the lowest loop of the bottom part of the last dc, go on like that until you have the wanted length.
Now comes the Trick …..lay flat on a table so that all the dc row is
straight, take the 1st dc and turn , make a SC [usa] on the Bottom
part, of the first Dc , put a marker, now make a Half DC, in the
bottom of the second dc , make Dc on the bottom of third Dc, and
work Dc from now on all the Bottom side of the 1st row,,,,, when you
come to the marker you might descide to make some lacy pattern , Both
sides will show thus upper of the row wil show one side of the crochet
and underside will show Other side of the crochet , But it is and
looks and feels like One piece …. mirjam
