I did the same thing. I saw a beautiful batik BOM, the Back To Nature with the tonga Batiks from Wing and a Prayer last year. I started it, the directions were confusing and my blocks looked like crap. As I continued on the blocks started looking better and better. I bought a little bit of extra fabric and redid the original ones that looked like crap.
It's certainly not perfect, my points are fantastic, but I am pleased with how my blocks came out overall.
Now squaring them all is where I need assistance. LOL.
Keep your head up and don't be intimidated by the experienced stitchers, they usually love to help the newbies.
