I know a lot of knitters don't like to knit garments because traditionally so many patterns call for knitting them in pieces and seaming them together. The process of seaming is not much fun, and it does take practice to be able to do it well.
That's one reason why so many people these days are interested in knitting garments that don't require piecing: projects worked top down, bottom up or side to side all of a piece, so that you basically just bind off, weave in ends and your project is ready to go.
Designer Kristen TenDyke offers 20 fun, pretty, casual patterns of this sort in her book Finish-Free Knits. This book is all tops, some of which are pretty simple Stockinette, others of which have lace or cables. All of them are worked in ways that keep you from having to sew seams when you're done, and they often use fun construction techniques to accomplish that goal.
This book has some really great stuff that I want to knit for myself, and I'll bet there's something in here that you would like, too, whether you hate seaming or are just impatient and want your project to be done as soon as it's off the needles.
