First credit where credit's due: I got the idea and inspiration from Freddy Moran. I got the book "collaborative quilting" and just couldn't stop looking at her extremely happy quilts.
I made the pattern myself and thise is how I did that:
Note: I'm working with CENTIMETRES instead of INCHES. You should find your own equivalent in inches!
First draw a square the size of your finished block. Make it easy on yourself and pick a size you can divide by 3.
Mine is 21x21 cm.
Mark the middle and where you divided it in 3. I made a mark every 7 cm, 'cause 21:3=7 :)
Now it's time to look for a pair of compasses and draw your first circle.
Diametre of my first is 14 cm
The small circles in the centre are appliqued on later. I used a threadspool as a template.
And that's all there is to it!
I cut the paper parts, added seamallowances to the straight lines,glued them on sandpaper and drew every piece on the fabric. Old-school piecing that is :)
Do not forget to add seamallowance to the curved lines. I eyeballed that while tracing the templates onto the fabric. I already had my sewinglines and since I sewed by hand, I had no problems.
A word about colour: I went from the idea that anything goes. If the outer circle had a purple dot, I sometimes chose a purple background for the inner circle. Other propellers are randomly put together just because the colourcombo seemed nice to me (and bright!)
