Okay, I found the library and the Pretty Poncho was very close. The shawl I saw, however, was done completely in what appeared to be chain sts, with a slip st in the middle of each 'run' of 8-10 sts of the previous row. From a distance it looked kind of like airy, lazy openwork fish scales (?-semicircles? sorry not sure how to describe..lol). As I looked at it up close, I could see the main body of the pattern appears to be nothing but chain sts, with shells formed on the ends of the rows (or possibly edged after body is finished?)
It was not only the simpleness of the pattern that appealed to me but the finished look. I'm just not that patient trying to come up with a pattern because I can't focus well, I don't have that much experience with crochet to guess at gauges and how to begin, and receive too many interruptions. With a pattern for a simple item, I can follow and not worry that I have to start over 20 times, get frustrated and quit, leaving my yarn bag to sit for weeks while my husband wonders why I left yet another project by the wayside...lol.
Any suggestions? Other places to look? If the store is open today, I may ask if they will give my phone number to the lady and maybe she can tell me (if she's the one that did it). I will certainly share if I find out. In the meantime, I appreciate any responses. Thank you!
