Knitting experiments are fun. You can try what’s possible with a range of techniques. So, after knitting my Garter Stitch Snowflake, I wanted to try something similar but with contours in a constrast color.
This doily (placemat, potholder …) consists of 60 short-row diamonds that stack up to be triangles which in turn form a (slightly angular) circle – or a spiky hexagon. It starts with a provisional cast on and is finished by grafting in garter stitch. It is quite fiddly and not a beginner pattern.

The pattern PDF contains

• written row-by-row instructions for knitting this piece – including 8 in-process photos
• an explanation (plus 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), weaving in yarn while carrying it (backwards and forwards)

The last picture shows the WS of the piece.
