What is this pattern called?

[HandsomeRyan]

What colors are you going to make it in?

Red and blue marble on a white background.

Question: do you use charm squares or layer cake squares?

Yardage.

It has some rectangles in it too. It has several different combinations for the HSTs. You might need a pattern for this one.

It does not require any rectangles. It could be done with rectangles but other than a few extra seams which have to be sewn, it is a lot simpler to just use squares the same size as the HSTs which is how the example I posted was done (you can see the seams).

You just need (using the colors of the example in my first post):
12 HSTs done in both colors
4 HSTs done in blue and white
16 HSTs done in brown and white
12 blue squares the same size as your HSTs
20 white squares the same size as your HSTs
+yardage for borders

Easy-peasy lemon squeezy.
