Sure you can make 4 HST at a time. Put 2 pieces Right Sides Together and sew all the way around the outside with a 1/4" seam. Cut diagonally both ways and you have 4 HST. The edges will be on the bias, but you can starch them to hold their shape through your sewing process. I think MSQC has a tutorial on this method and I think you can do a search on QB for the size of square to start with so you will have the correct size finished HST block. Good Luck.

I use Thangles to do speedy HST's - cut your strips of each fabric the length you need to do four HST's of each of the fabrics plus an equal number of strips for the background. You can still chain piece using Thangles. Going to be a pretty quilt - but be sure the end block on the right edge of row four is turn around correctly before you sew it in to the row. Your diagram has that block turned in the wrong direction - which made the "ladder" extra long. Looking forward to seeing the finished quilt. Do enjoy those fall colors.

Omg, Jan, however did you catch that? You're really good! It totally got past me...

Since this quilt is only two blocks . . .I would make a list of pieces in each block, but only do one block at a time.
From the list of pieces for the individual block, I would note how many of each color . . .then strip piece all like blocks, cut and sew together. Then do the same on other block.

Both break down to squares and half square triangles. I'd use triangle papers to speed up the half square triangles. Easy peasy. It's a nice looking quilt.

GAH, how long have I been staring at that and not seeing the 'oops'? Thankfully it's an easy fix at this stage. Thank you!

Here's how I would piece the second block. Just my 2 cents worth, but it keeps the orange triangle "whole". Depending on your fabric, that could make a difference.

Love this design!
May I borrow it? It would be perfect for my "peacock colors" quilt.

Absolutely! The pattern is called "This Way and That Quilt" by Jean Ann Wright. Hers had one less horizontal and vertical row, but I wanted mine a bit larger. :)

Love how mine in the peacock colors is coming along! I'm following Debd's diagram for doing the second block. It works great. Thanks for the inspiration and suggestions. Love this board! Can't say that enough times.
