I worked on round 2 of my scrappy medallion quilt.
I added a row of 4.5 inch HST's.
Here's how I did it.
One neutral and one coloured
2 - draw a diagonal line 1/4 inch from the centre diagonal line of the light square.
3 - sew on these two diagonal lines
4 - cut in between these sewn lines as shown above.
5 - iron seam open
6 - trim hst to 4.5 inches
You should have 2, 4.5 inch hst's.
You will need 2, 4.5 inch hst's in the following colours.
Black, brown, green, dark blue, medium blue, yellow, orange, pink, red, raspberry, purple
You will also need 2 plain 4.5 inch squares of background colour,
