Dovetail Designs

Founded in 1998 by Val Love, the company's goal is to create stylish patterns that are easy to wear, and to find the simplest way to construct them.   They create knitting and crochet patterns for all skill levels.

Most garments are worked in one piece; either top down, or bottom up with shoulder seams. 
Sleeves are usually set-in (stitches are picked up around armhole) and worked in the round from shoulder to cuff.  Optional short rows at top of sleeve give a tailored look and a trimmer fit. All patterns give inch and metric measurements and have helpful charts, diagrams, and stitch guides.

The company offers corrections for download on their website.
