Q: Use a tinting brush to apply some bleach to the strand of hair that's on the foil. Start applying the bleach from the middle of the strand, and work your way down to the ends. Use more bleach on the ends of your hair, and less bleach in the middle. You won't be bleaching the lower section. This is what will create a highlight rather than an all-over ombre. You can do this with a clean tinting brush or with a toothbrush. How far up you blend the bleach us up to you. You can blend it all the way up to your roots, or you can blend it up just two-thirds of the way. This blending step is important. It will prevent any harsh lines and help create the ombre. Use a light, feathery touch. You want the bleach to get softer the closer you get to your roots. Use a combination of vertical and horizontal strokes so that there aren't any harsh lines. Fold the bottom edge of the foil one-half to two-thirds of the way up. Fold it a second time to lock your hair in. Next, fold the left and right side edges of the foil over to cover the bleached section completely. The foil will prevent the bleach from transferring to the unbleached potions of your hair. Do not include the unbleached, lower layer in the foil packet. Pretend that it doesn't exist. Weave the handle of your rattail comb through the second strand that's draped over your other shoulder. Slide a piece of foil under the upper strand, and apply the bleach to the midlengths-down. Blend the bleach in towards your roots, then fold the foil around the bleached hair. Undo your bun, and let down another layer of hair. Pull the rest of your hair up into a bun. Split the second layer into 2 to 3 sections, and highlight them using the same method as you did the first layer. Remember to split each section into an upper and lower layer, like a subway sandwich. Only bleach the upper layer, not the lower. Once you finish a layer of hair, let down another layer from your bun. Apply the bleach to 1 to 2in (2.5 to 5.1cm) wide sections of hair. Remember to split each section in half, like a subway sandwich, and to apply the bleach only to the upper layer. Work quickly, otherwise the lower layers may end up too light. If you want a more natural look, blend the bleach closer to your roots once you reach the strands around your face. If you run out of bleach and/or the application process it taking a lot of time, make a second batch of bleach that contains a developer with a slightly higher volume than the first. Low-volume bleach acts slower while high-volume bleach acts very quickly, so applying in this way may prevent the hair you bleach first from turning out lighter than the rest. For example, if you used 20 volume developer in your first batch, use 30 in your second one.
A: Apply the bleach to your hair with a tinting brush, starting from the middle. Blend the bleach towards the roots. Wrap the foil around the bleached section of hair. Repeat the process for the other section. Let down another layer of hair, and repeat the process. Continue to highlight your hair, but work quickly. Finish with a higher-volume batch of bleach if necessary.

Q: A physical card is much nicer than only sending an email to say thank you. It's a more personal gesture and it is more meaningful than an ecard or email. It will also give your teacher a physical keepsake to remember their old students by. If you aren't sure of your teacher's mailing address, then you might need to do some investigating. Some options to try for locating the address include contacting the school directly or contacting the alumni or local teacher's associations. If the teacher you're thanking is a high school teacher, then you can simply address the card to your teacher at the school's address, which will be available on the main page of the school's website. If you're thanking a former college professor, then things get a little trickier. You'll need to either call the office of the department in which your professor teaches to find out their specific mailing address or search the school's website to find out the address of a particular department. For example, if you want to thank your former Political Science professor, then you will need to call or search the website of that department to find the correct mailing address for your professor. Do not send the card to the general university mailing address, as that is for school administrators, not faculty. College faculty are often very mobile, more so than K-12 teachers, so they might not still be teaching at the school where they taught you. If this is the case, you can contact the department office and ask for a forwarding address for them. When you go shopping for a thank you card, keep in mind what you want to convey with your card. Do you want it to be serious or would you prefer a more playful message and design? Make sure the tone of your thank you card is appropriate for the relationship you have with your teacher. If you're unsure, err on the side of caution. You'll be personalizing the card, so pictures on the card are less important. A handmade card is also a wonderful gesture! It shows a little more effort on your part and is easy to create. You can simply fold a piece of paper in half widthwise and include a combination of illustrations and words on both the inside and outside. Your card should begin with "Dear [teacher's name]." To ensure that your thank you note doesn't feel stiff or sound strange, address your teacher the way you addressed them in class. For example, use "Ms. Smith," "Dr. Jones," or "Amy," depending on how you referred to them in class. Likewise, if your college professor has their doctorate, use "Dr." and not "Mr." or "Mrs." If you're unsure of their proper title, this will require some research on your part. Check out the university department's website. There is usually a faculty page with brief biographies and resumes that will let you know whether "Dr." is the right title to use. Teachers love to get positive feedback from their students, so you should let them know specifically what they did that endeared them to you. For example, did they stay after class to help you understand some course material better? Did they make an ordinary lecture interesting or inspiring? Were they flexible or understanding when you had personal issues during the school year? Be sure to say thank you, but also make sure to include specifics. Begin your letter with "Dear [Name]" and make sure that you use proper grammar and punctuation throughout. Avoid using "hey" as your greeting because that's not a respectful, professional greeting. If you're worried you'll make a mistake while writing, try writing your message on a separate piece of paper and then transcribing it onto the card. This way you can avoid having to scribble out or white-out over mistakes.
A:
Deliver or send a handwritten note. Make or purchase a thank you card. Address them properly. Specify why you appreciate them. Keep it professional.
