But, looking at your pic, I see a major EPP project.

IOW each of the parts in the pic, would be cut as a paper template, like you would doing hexies.

Except each of these are different shaped than a hexie! You'd still use the same process/method to stitch them together, by hand. Instead of paper, I find it easier to use card stock ... either purchased or old greeting cards etc.

The centre "star", I'd find the centre point, then draw in the lines to make a multi piece unit.

Look forward to seeing yours come to life!
