ohhhhhhh beach .... want.... :-D
But I would be grilled in minutes :-DDD If I had a beach nearby I would probably also try to knit or crochet, but as you told, not sure how practical it is.
Your pink mat is super nice, and I also can see a pattern in the flecks (you should tell others, that you made this possible by elaborate math to simulate a quasi-random colour distribution)
And lovely beach photo of you <3
