Garter Stitch Snowflake

I've always wanted to do a big lacy half-circle shawl all in garter stitch. This doily started out as a test piece for that kind of shawl. However, I liked the small piece quite a lot, so I tried to figure out how to do it in a seamless full circle – and here it is as its own knitting pattern. 

This doily consists of diamonds that stack up to be triangles which in turn form a (slightly angular) circle. It starts with a provisional cast on and is finished by grafting in garter stitch (just before knitting and binding off the last stitches). It is NOT A BEGINNER PATTERN.

The pattern PDF is 12 pages long and contains

• written row-by-row instructions for knitting this piece – including 6 photos
• schematic of the construction, i.e. how the diamonds stack up to create the whole piece
• chart(s) of one diamond
• short photo tutorials for the following techniques
  • provisional CO with a crochet hook and undoing it
  • grafting in garter stitch
  • short rows with wrap and turn and picking up the wraps
  • crochet CO (at the edge of a knitted piece)
  • backwards loop CO

To knit this piece you need the following materials

• about 250 metres of light fingering weight yarn (for the piece in the photos I used Creative Melange Lace by Rico Design, colorway 011)
• 2.5 mm knitting needles
• a crochet hook of a similar size (I used a 2.5mm hook)
• scrap yarn for the provisional CO
• a tapestry needle – for grafting and to weave in ends

Knitted in Light Fingering weight yarn the finished piece has a diameter of about 42 cm.
