Zig Zag Custom Quilt in progress #1

I was delighted to be contacted by Kirstin through my Etsy shop about making her a Zig Zag Quilt similar to this one. This post is a way of keeping her informed of my progress (I promised to deliver the quilt by end of April) and also to show a couple people out there who asked me for more info on how to make such a quilt. To that effect, I have also started measuring how much time I spent on each step of the process… I estimated about 40 hours to complete the quilt. How long will it actually take ? Watch this space !

Step 1 – Selecting and cutting fabric – 3 hours
The finished quilt will measure 70in x 70in, 10 blocks x 10 blocks.
To obtain a square of the required final size of 7in, you need to cut it 8in x 8in. You will lose half an inch during the creation of the half-square triangles and half an inch when assembling the squares.

This quilt requires :
10 squares of assorted orange fabrics (preferably different prints)
10 squares of assorted mixed orange and yellow prints
10 squares of assorted yellow fabrics
20 squares of assorted grey fabrics
50 squares of white cotton for the background and this is what the stack looks like :

Step 2 – Creating the half-square triangles – 3 hours
Take a white and a colour square, put one on top of the other, right side to right side. Trace a diagonal line on the top fabric using a sharp pencil and sew a straight line 1/4in on either side of that line.

Using a ruler and a rotary cutter, cut along the pencil line to separe the half-square triangles.
