Quick update. I found a better microfilm copy of the Democrat and Chronicle from October 30, 1935 and can tell you this.
In the period between 1932 and 1935, the Knitting Section of the Rochester Branch of the Needlework Guild of America took in 4,385 hand knitted garments from about 100 expert knitters. The bigger number, 15,425 new garments, that is referred to at the end of the article must refer to sewn garments as well. After all, it was the Needlework Guild.
So. Our intake though the community knitting program of the Rochester Knitting Guild today is not so shabby after all. For the past couple of years, we have collected over 1,000 items from our members each year. I know it's not a competition, but it's still interesting. I'll get back to my mittens now.
