Gauge is not really important. The lace panel opens up nicely when the gloves are worn, giving extra stretchy quality to the knitting. The samples measure about 8 in/20cm in total length. Unstretched they are approximately

6in/15cm in circumference. If you really desire a larger glove, go to a needle size US 8/5 mm.
The yardage is for two gloves.
The pattern is written and has a chart.
