This pattern is designed for working on circular needles (short length ones or longer length via magic loop) but is easily adapted to working on DPN’s, (pattern includes notes on this)

The pattern does not include specific details on working double knitting, (but does have some general notes)

It has some challenging aspects--
a provisional cast on
double knitting
charts
and a grafted finish.

This pattern is designed in a single size, but size can be adjusted by changing the gauge --the pattern includes notes for alternate gauge.
