bum! sorry about the above 
i am crocheting a cardigan for my dd. it is the first garment i have crocheted.
it says the tension needs to be 22 stitches to 4 inches. i counted and i am doing 22 stitches in 3.5 inches.
i am doing the size up for her to grow into but can i get away with that half inch difference or should i start again?
