[COLOR=Black]and how should i modify my gauge?[/COLOR][/COLOR][/FONT]

You need a larger needle and double your yarn or use thick yarn. 10mm is size 15 US. The gauge means you would be getting 2sts per inch, 4 rows per inch. You might be able to make with the yarn and needles you have (how thin is it, DK, worsted?) and double the number of stitches, but you’d have to knit a sample to see how that would work out.
