Sewing the Seasons

They taught me to crochet and also to tat (a method of making lace with a handheld shuttle ). I haven’t had the patience for either craft in a long time, and have probably forgotten how.

Heath Canada’s Pesticide Compliance Program (PCP) is responsible for promoting safe use of chemicals , as well as monitoring and enforcement, to make sure registered fungicides, insecticides and other agricultural chemicals are used according with their legal label.
