Biting off more than I can chew

I have this awful habit of taking on too much. The word "no" is not my friend. This time I think I may be taking on too much in terms of crafts. I have already thought of presents that I can make for four people. Luckily its only August so I should have time but there still must be time for hubby, kids, work and church stuff. Someday I will learn the word "no"...
