It has been so fun to already see blocks popping up in the Virtual Quilting Bee Flickr group. One of my favorite things about quilting is seeing the variety of colors and fabric choices people use.
I've decided to make my own version and spent the morning pulling fabrics from my stash in a new palette I've never tried. It's a bit of a break-away from my traditional primary-color palette that I use most often. I'm kind of excited. Most of the fabrics are bits and pieces from favorite fabric collections from days of yore like Denyse Schmidt's Hope Valley, and a few of her collections from JoAnn's, Joel Dewberry's Deer Valley plus I've thrown in a bunch of the recent Bike Path Dots by Alison Glass that I've been itching to create with. I'm excite to play with this stack.
When making my block, I remembered that a couple of people have asked me for a quick tutorial on squaring up half-square triangles. So here's a quick explanation: Half-square triangle (HST) blocks are one of the most versatile blocks in quilt-making. They are quick and easy to make as Sherri showed by drawing a diagonal line on the back of one of the squares, matching the two prints right-sides together, and then sewing down either side of the line with a scant 1/4" seam allowance.
Then cut on the drawn diagonal line and press both blocks open and voila: two identical half-square triangle blocks! As Sherri mentioned in her tutorial, you are going to want to square-up these particular HST to 2 1/2 inches - that means trim them to the right size and make the sides straight - or "square". I personally like making my HST's slightly large and squaring- up the block when I'm done because it makes the blocks so much neater to work with.
Even with the most careful of sewing, when you sew on the diagonal you are sewing on the bias. Drawing that line and sewing before you cut, will help keep the diagonal edges from stretching but there will still be some misshapen edges on those blocks. Squaring-up will make things nice and neat, not to mention the right size, in many cases.
When squaring-up a pieced block, you want to be careful to keep that diagonal seam running from corner to corner. If your ruler has a diagonal line on it place that line right over the seam. This will keep your seam centered and your block square. If your ruler does not have the diagonal line, place the corner point of the ruler over the seam and make sure the point you are measuring to (in this case the 2 1/2" point) also on the diagonal seam at the other end.
Hope that helps!
And just a reminder - I'm answering questions as much as possible in the comment sections of each post. Let me know if I've missed something. Thanks again for playing along!
