I also knitted these coasters, based on a pattern from Purl Bee, to be given to a friend with hot chocolate for Christmas.
I knit all of these while traveling on planes, trains, in cars, in restaurants and bars, etc. They are easy and portable and I liked the results. I would like to find to finish the coaster edges more cleanly next time I knit them, though. They were all knit in superwash merino so they are machine washable.
