That would be very easy to paper piece ... and very easy to draw the paper pieces yourself with the aid of Word or Excel.
Each block is made up of 4 triangle units. Each unit has 3 fabrics - center blue triangle, thin black border, and wide neutral. You can draw this triangle easily and make as many copies as needed ... and whatever size you want.
Once you've made all the triangle units - sew four of them together and use that narrow black stripe to match your units. Because you will be working with bias edges I would keep the paper on the triangle units until after you've joined them into a square.
Bear in mind that you will need some half square finished blocks for the side triangles because this pattern is set on point.
Once you have the squares completed, remove the paper and add the sashing.
It's a very pretty quilt.
