She was showing a technique for making half square triangles that blew my mind. Based on what I saw Marianne and Jo do on the show, I tried the technique and was pleased with the results.<\/p>\n<p>I found this half square triangle (HST) technique to be one of the best I have seen. It is straightforward, there is a minimum of dealing with bias and the squares magically appear all at once.<\/p>\n<p>There are a number of different tutorials for making HSTs (half square triangles\/triangle squares) and I link to some of them below. My technique below makes 8 HSTs at a time and can be used for the <a href=\"https:\/\/artquiltmaker.com\/blog\/2011\/04\/making-a-double-pinwheel\/\" target=\"_blank\" rel=\"noopener noreferrer\">Double Pinwheel<\/a> that is part of the <a href=\"https:\/\/artquiltmaker.com\/blog\/aq-projects-tutorials\/aq-tutorials\/quilt-class\/\" target=\"_blank\" rel=\"noopener noreferrer\">Quilt Class tutorials<\/a>.<\/p>\n<p>This is more of an informational tutorial than a tutorial related to certain blocks. HSTs are a component in many, many blocks designs, so learning to make HSTs using this method will come in handy<\/p>\n<p>I started with 5&#8243; squares, which is the size they used on the show. The 5&#8243; squares make 8 HSTs. I thought it would be a great way to use charm packs.
