I gave up on a purchased curriculum too.
For themes- I just started gathering my stuff and getting organized. I bought some rubbermaid type tubs for each month and put everything in it. There are pics in this thread
https://www.daycare.com/forum/showthread.php?t=41656 I may eventually separate out and organize stuff theme but for right now this is a start. I also keep ideas of things to do for each theme on my computer. I think eventually I will print it all and get it into a binder but since I'm still new at getting organized I keep adding ideas to each theme and it would be pointless to print anything yet.
For my alphabet resources- I'm still not sure how to organize all of that yet. I use some stuff from the Letter of the Week curriculum from Confessions of a Homeschooler.
