HST's: the four patch version

Simplest classic layout

The four by four 4-patch version of a 12" HST block lends itself to lots of  arrangements. This time the squares are cut 4" and after sewing trimmed to 3.5" unfinished to finish 3". If you didn't want to trim you would cut squares with 7/8"  added to the finished size.
Value (light and shade) plays a major role in the appearance of these blocks. I made up a set of scrappy 3" + seams HST's and set them out in different ways all making use of negative/positive effects. Secondary patterns will form when blocks are set side by side either in the same light/dark arrangements or reversed. These endless possibilities added to endless fabric choices are what makes patchwork fun and so so fascinating.

"Lozenge" layout which will form secondary pattern when
set side by side.

Diagonals which can be turned this way and that.

Easy Angle

Today has been vey productive. Yesterday I sandwiched three charity quilts and today I machine quilted one of them. In the evening it was my turn to do a presentation for Quay Quilters and I'd chosen "Special rulers" as my subject intending to teach myself as much as other group members as most have been little used and some were sealed in the original packaging. First off however was one I have always used, the EZ Easy Angle which enables you to cut half square triangles from the same size strips as the corresponding squares - very useful for jelly rolls when you don't have the option of cutting 2 7/8" squares in half. Also if you layer the strips right sides together you can just pick up the paired pieces and sew - must be the quickest way.
For my demo I was making 3" finished units so cut my strips 3.5" inches wide.
And I've now added a picture of a sample block composed entirely of HST's made from Cherrywood fabrics.
