Lady of the Lake is an old block, first published by the Ladies Art Company c. 1895. I have made the little half-square triangles ½” finished; as tiny as they’ll go.

You’ve practised and practised your Half-Square Triangles, so now, I want to introduce you to a variation. What if you didn’t join just two squares of fabric to make a Half-Square Triangles, but instead, joined one square of fabric and one pre-pieced block? You could get something like today’s block!
This simple little block will open up some more opportunities for you. I’ve called it Sailboat, because I think it looks a lot like a boat with a triangular flag against the blue sky on the sea. I’ve used a modicum of artistic licence for this naming, as it somewhat resembles a Sailboat block documented by Jinny Beyer:

Sailboat, Reference: Beyer, p. 56
Also, in naming this block Sailboat, I have eschewed the many other names attributed to it. EQ7 calls it Y Block. Molly Malone gives Pigeons in a Coop from Quilter’s Newsletter, Rocky Mountain, Shadow Box and Waste Not, Want Not. I hope you’ll forgive me this once; Sailboat is so evocative.

This block was introduced to the quilting world in circa 1906, when it was published by Clara Stone in Practical Needlework. Not much else is known about the block; but it’s good practise for those Sailboat blocks we discovered yesterday.

This block is often called Cotton Reel, or Quarter-Square Triangle for obvious reasons. However, we’ll call it Hour Glass … I’ll explain more tomorrow. There is a specific tutorial for this block, as it is utilised in many other blocks.
