Since I borrowed his pinch/punch block idea for a chart and have been wanting the books for the double knitting cable patterns anyway I bought everything Fallingblox (Alasdair Post-Quinn) has printed. His Parallax scarfs aren’t an exact match but I should have enough yarn left that one would be a match for the hat I’m making.
If you like double knitting I recommend them. He says Double or Nothing is for more advanced and Extreme Double-Knitting covers beginner better. I think Double or Nothing covers beginners enough if that one had the cabled hat pattern a beginner wanted and they only had $17 they could fill in whatever is left out with free beginner patterns and get by with just that book.
Main differences I see is Extreme Double-Knitting covers 2 pattern (i.e., words on both sides) and 3 or more color. Double or Nothing is more into textures and more complete.
Even the Parallax patterns cover the basics.
What makes me happy is a double knitting long-tail-ish cast on that won’t have the too short of a tail problem. The hats and maybe some scarves are the only patterns in them that interest me.
Double knitted cabled hats, double knitted entrelac hat. Looks like I’ll be on a DK hat kick for quite a while.
