Original blouse based on grandmother's square 

Today we knit just such a blouse using elements of the grandmother's square.
Grandma's square is usually knitted from groups of double crochet stitches of 3 stitches each.
In the corners of the square, we knit 2 groups of columns separated by 3 air loops
We start with a chain of 30-40 air loops, unfold the chain and knit 1 rowd of single crochets along it. We do not knit 10 loops to the edge and make 10 air loops (as on the rest of the chain)
I unfold the knitting and start knitting: 3 air loops for lifting, 2 double crochets in one loop, skip 2 loops, knit the second group of 3 columns, skip 2 loops, 3 columns and so on.
In the last loop I knit 3 columns, 2 ch, 3 columns 2 ch, 3 columns and start knitting on the opposite side of the chain of the group of columns exactly opposite those that are already knitted.
And so on to the end of the row.
I change the thread and start knitting groups of columns between the groups of the first row. You know how to knit corners. In each corner we knit 2 groups of columns separated by air loops.
In each new row, change the color of the thread.
When the canvas is finished, we begin to knit the back.
She can be knitted in the same way, but without a cut, or you can just use one canvas and one color.
We tie the incision and sleeves and sew the halves of the blouse.
We are great and were able to knit an original blouse based on a grandmother's square.
