Your question about a bill organizer inspired me to make a multi large brown, 12"X10" envelope- bill/ mail organizer. I've come up with labels that I hope work for me as I organize my mail and bills. These are the categories that I've come up with:
Daily Receipts Jan.-April
Daily Receipts May-Aug.
Daily Receipts Sept.-Dec.
Correspondence To Do
Big $ Receipts
I'm covering the envelopes with patterned paper and will add embellishments and textures to each envelope. Thinking of binding envelopes with large circle rings.
When I'm finished, I'll post pictures in my gallery. Again, great idea!
