Once upon a time Karen and I decided to do a CAL ( crochet along). That's when everyone follows the same pattern and works on it approximately in parallel time but not necessarily the same color, yarn or size. The "knitters" thought they would do the same.
This particular sweater is from Crocheted Aran Sweaters by Jane Snedden Peever, which I believe is now out of print. We both had the book and had always wanted to do this particular sweater.
Karen used Cascade 220, which is a wool and cotton mix. I used Lion Brand's Wool-Ease, which is wool and acrylic. The shade is natural heather and not the usual whiter color that Karen chose. Karen's sweater seems more polished and dressy, while mine is more rustic and casual.
The closeups are so you can see the details of the stitches.
The knitters, however, have still not got their act together. Somebody is swatching, somebody is looking for yarn, and somebody actually has a back almost finished. But they didn't even get the idea of a KAL right! They're all using different patterns.
