How to use gauge to fit different needle and yarn?
I am attempting a baby blanket but the needle and yarn that is used is different from my needle and yarn. This is the gauge given:
14 sts = 4 inches (10 cm). BE SURE TO CHECK YOUR GAUGE. When you match the gauge in a pattern, your project will be the size specified in the pattern and the materials specified in the pattern will be sufficient. If it takes you fewer stitches and rows to make a 4 in. [10 cm] square, try using a smaller size hook or needles; if more stitches and rows, try a larger size hook or needles.
That blanket is made on US 11 needles with a light bulky weight yarn. But I am using US 7 and worsted weight yarn. The pattern says to cast on 123 stiches, so what should be the new amount for me to cast on? Thanks
