Well I realise I really should have posted this information several months ago but honestly I never thought of it.
When I first started I did the blocks one by one. Designed it, traced the templates onto template plastic, cut fabric and then sewed it. Then did the same for the second block etc.
After a few weeks, I found that it was best to get ahead with cutting. From then I went with what I felt like doing.
Most weekends I cut the fabric, when I was stressed I designed, (designing is really just drawing lines and colouring in) and when I wanted to relax I sewed. It worked well.
The smallest zip lock bags were perfect for storing the cut fabrics. I would place several blocks into the same bag along with the picture of the design. Once I thought I didn't need to include the design as I was feeling too lazy to draw it out again. Remember when I started this project I drew EVERYTHING by hand. I drew the original design on some graph paper, then onto template plastic (yes I did start with template plastic)...... anyway as you may guess it was next to impossible to work out which design belonged to which fabric. Thankfully I only had a few blocks in that bag and knew they had come from one of two design sheets.
