I haven't made any other patterns from the book. I used just one strand of yarn and it turned out just fine. I did cast on more stitches than it said to since my yarn was smaller. My daughter bought 4 balls of the Bernat Satin yarn on clearance at Michaels. I thought that it wasn't going to be enough so I bought two more balls of it. I used 5 and 3/4 of the last ball.What was left was not enough to make something with so I use it fro practicing pattern stitches of different kinds of stitches.
My daughter used the blanket I made as a baby shower gift and when it was pulled out of its gift bag, my daughter said the family members of the pregnant girl went gaga over the blanket. They thought it was machine made. My daughter told them it was hand knit, she should know she bought most of the yarn. It was a little bigger than a regular baby blanket because the mother wanted one to be big enough to go onto a toddler bed. I hope that the info I gave you helps . Just trust the pattern instructions and it will turn out just fine.
