Partial progress:
These are Hitomezashi patterns. Each vertical line has two possible states; ditto for each horizontal line.
Top left: 0010100 horizontal, 1100000 vertical
Top right: 0001100 horizontal, 1100011 vertical
Mid left: 0000100 horizontal, 1100100 vertical
Mid right: 1111000 horizontal, 1101000 vertical
Bot left: 0100100 horizontal, 1100110 vertical
Bot right: 1010100 horizontal, 1100101 vertical
Any of these codes could be flipped or inverted from their intended readings. Seven bits make me think ASCII.
EDIT:
The first one is not a true Hitomezashi pattern. The bottom row of horizontal lines does not work.
