My first quilt was a Lone Star which is really not a beginner quilt, but I guess I'm just a glutton for punishment...LOL
First I tried the strip method and mine didn't work either, so I feel your pain. I think they may have been better if I had starched heavily before cutting, but I didn't know to do that. Anyway, I ended up cutting individual diamonds to make my star and used the diagonal strips in the border.
I know this isn't much help, but I do understand your frustration. Maybe these great quilters here can help. Your fabric choices are wonderful.
Good luck!!
