Test Tubes Quilt Block

October is Science Month for Quilt Block Mania, and we have a collection of free* blocks for you from across the science spectrum.

I've gone back to the chemistry lab of my high school and designed a foundation paper pieced Test Tubes block for you. This one is suitable for more confident paper piecers, but don't let that put you off if you're not there just yet. Practice on a few simpler patterns (such as my Festive Forest, Mini Flocks, or last month's Twisted Log Cabin) and then dive into chemistry.

Of course, as with all the blocks you can make them in any colour scheme you like. I'm thinking I might put all my Quilt Block Mania blocks from a year together into a quilt, so I'm using my signature colour scheme of bright solids for all my samples. 

My FPP patterns all include a colouring page so you can try out your own colour combinations before cutting into your fabrics. Grab your box of crayons or coloured pencils and let the creative side of your brain do the work. Here are a few options to get you started.

  • Hi Susan, thanks for letting me know. The link seems to work for me when I type it out, but not when clicking on the blog post for some reason. Here it is, though https://www.duckcreekmountainquilting.com/blog/2021/10/4/science

  • The link for Duck Creek Quilting doesn’t work.

  • That’s wonderful, Lori. I’ve always loved chemistry, especially the “creative” kind where we got to mix things and see what happened ;-)

  • this is wonderful. thanks for the pattern. I remember my dad working with lots of test tubes. He was a chemist for his own company
