How can I mend my grandson's polyester, no-iron baseball pants?

i have a brand new polyester tee shirt i got less than a week ago. tonight, i lit a match and a spark fell on the shirt. it has a small hole right in the front of the stomach. it made me VERY mad lol. my stepdad told me that they have a vinyl repair kit at wal-mart that would mend the hole. then, whatever color the pants are, go over the patch with nail polish that matches that color.
