I hope you are all well and keeping busy with things that make you happy, including sewing.
For Block 1 of our Modern BOM we will use four fabrics...3 fabrics plus 1 background fabric.
The fabrics I chose happen to be colour coordinated with the block's instructions. If yours are not, I suggest numbering them 1, 2, 3, and 4, and make notes on the instructions which are which. This will hopefully help avoid confusion.
As it says in the instructions, you will cut out 4" x 8" rectangles...2 from each fabric. This is if you want to use the method in the instructions for constructing half-square triangles (HST's). You can use your own preferred method if you want, I think we all have our favourite. I decided to do what the pattern instructs us to. I always like to try "new-to-me" methods because you never know....it may become my new favourite method!
You will then trim the blocks to 3.5". I know it's a bit tedious to make the blocks bigger than you need and then trim them down, but this results in precision...a much desired thing in piecing quilts!
On a side note, for trimming HST's I really like using the Bloc Loc rulers. They definitely are not a necessity, but it is a ruler that I'm glad I purchased (lol, not like a drawer full of ones that I don't use).
