Shadow Magic is a fantastic, squishy, oversize shawl worked in garter stitch, with eyelet rows in contrasting colours. The name comes from another of my hobbies, breeding and showing pedigree Guinea pigs; it is named after my first ever Best In Show winning Guinea pig "Tamar Shadow Magic".
The eyelet rows are all worked with 10g minis. Each row uses less than the full mini but if you plan to have 10g of each colour you will have plenty. You will need approximately 350 g (760 m) of the main colour.
Shadow Magic was designed as a large, oversize shawl so gauge is not that important. My finished, unblocked measurements are 1 m X 1.8 m X 2.1 m.
