It is a pity that the sneak peak inside this book doesn't show you the best it has to offer because it is filled with some of the most gorgeous sweater and cardigan crochet designs that I have ever seen. The aran sweaters on the back cover are absolutely gorgeous. The small pic really doesn't do them justice. The cabled aran does a great job of showing off Melissa Leapman's design genius and no longer makes me envious of knitted cable arans. If you are looking for spring and summer sweaters, you will not be disappointed. There are many gorgeous ones here as many designs use the lighter DK and sportweight yarns.
As I expected from Melissa Leapman, the instructions are very thorough. Every pattern comes with a diagram with the measurements noted. I find this extremely useful as proper fit is essential to the success of any garment. I personally tend to not meet the right guage height requirements when my width is perfect so the charts really help me to make the proper modifications. Speaking of fit, nearly every sweater featured in this book has inset sleeves which not only make a better looking garment but a more comfortable fitting one as well. In addition to the instructions, there are several tip tidbits to be found amongst the patterns throughout the book such as alternate design/color suggestions and tips for a more professional finishing.
The yarns used are all fairly easy to find or easy to substitute with another yarn. The sizes range from S-XL but there are quite a few designs that will go up to 2X as the bust measurements go up to 54 inches on some designs.
If you only want one crocheted sweater pattern book in your collection, "Crochet With Style" should be your first pick.
