Many thanks to my sister Mrs. Sacco for providing me with proof of my youthful knitting, left. This must have been in 1971 or so and I was still deep into Granny Squares.
I remember buying this yarn at the Yarn Store on 10th and Bloomfield in Hoboken. It was a very bright white Red Heart acrylic and the shawl took two skeins which set me back about $1.50. I also bought a red size J crochet hook that day, which I still use.
Here's the pattern: Chain 1 and turn. In the single chain, double crochet 3, chain 2, and double crochet 3 again. This makes a point. Chain 2, turn and do 2 double crochet in between the first and second crochet, chain one, make a point at the point, chain one, then 3 double crochet in the space between the last two DC.
Chain 2, turn. 2DC in between the first and second DC, Chain 1, then 3 DC in the gap created by the chain in the prior row, ch1, make a point, 3 DC in the gap, ch1, then three in the space between the last two. Repeat this row until it is long enough to provide shelter for a little first holy communion girl.
