I'm in the process of making curtains for the livingroom and altering old curtains for new windows. I've acquired a lot of savvy from my experience and would love to share it with you.
1) Take a refresher course in math before buying material. That way you won't have to look "dumb" when the clerk asks you how many yards you want.
2 It is smart to listen to the clerk who has way more experience in figuring out yardage than you do.
3) Listen to your husband (if he happens to be with you).
4) If you didn't listen to your husband OR the clerk and have to return to the store for MORE material, try to find a different clerk to wait on you. (Hint: less embarrassing)
5) Avoid sticking yourself with straight pins. It creates pain, and at times, blood.
6) If you notice blood stains on the material, follow this advice I heard somewhere: spit on the blood. Well, they didn't exactly say spit, but the idea is the same...use your saliva which has enzymes that begin to act on the blood stain before you make yourself get up and wash it out.
7) If you can actually make these curtains look nice, Congratulations, you have achieved your goal.
