For everyday use, opt for a sturdy, washable fabric like a cotton-polyester blend. Canvas, while difficult to sew, will also last a long time. If you're a sewing novice, choose a solid-colored fabric so you don't have to worry about matching up the print when you sew the pieces together. On average, you'll need 3-4 yards of fabric to cover an armchair. Lay a piece of tracing paper, newspaper, or muslin over the largest section of the chair and trace the shape and size. Repeat for each section, working from the largest to the smallest areas. Feel free to maneuver the chair as needed if you want to lay it flat on the paper to get more precise patterns. Be sure to account for all parts of the chair, including the front, back, seat, and arms. Alternatively, you could measure each section of the chair and use the measurements to make your pattern. Label each piece of the pattern so you don't get confused later on. This is to account for the seam allowance and hems. Trace a new line around each piece of the pattern to include these increased measurements. Then, cut out each piece of the pattern. You only need to add a few pins to each piece to ensure the pattern doesn't move. Use tailor's chalk to trace the pattern onto the "wrong" side of the fabric. Press down the edges of the pattern with your fingers as you trace around it. Use the edge of a ruler as a guide when drawing straight lines. If you're using printed fabric, make sure the pattern matches up in a way you like. Stay as close to the lines as you possibly can. If you are having a hard time cutting the fabric, opt to cut outside the lines instead of inside the lines to ensure there's enough fabric to cover the chair. Wipe away the tailor's chalk with a cloth when you are done. Refer to the newspaper templates if you need help determining which piece is which. Insert the pins in the same direction as the edge of the fabric. Join the back pieces first, then add the front pieces and finish with the arms. Before you start sewing, carefully put the slipcover over the chair to ensure it fits. Make any necessary adjustments by removing the pins and realigning (or replacing) the necessary sections. the pieces together and hem the edges. Use a sewing machine to sew the pieces together. Sew them in the same order that you pinned them to make things a little easier. Then, hem the bottom portions for a finished look. Use 1412 inch (0.641.27cm) hem allowance. Once you're done sewing, all that's left is to put the slipcover on and enjoy your reupholstered chair.

Read all assigned readings. Write down any new vocabulary, theories, models, graphs, or measures. Notate any questions you might have. Read an article's introduction and conclusion carefully. Authors often use the introduction to outline the lecture's material. The conclusion could serve as a summary and help you see if you missed anything. Plan to spend two hours of studying for every one hour in class. When taking your economics classes, try to sit in the front of the classroom. Your teacher is more likely to see you, recognize you, and be willing to help you. Additionally, there will be fewer distractions (e.g. other people's laptops) to keep you from the lecture. When your professor is giving a lecture, take thorough notes. While you don't need to copy every word she says, try to craft an outline of her ideas. Create a wide lefthand margin for summarizing content. Fill in each segment with sub-points and facts. Write down any important definitions. Leave a smaller righthand margin for your own thoughts on the material. If your professor says, "this will be on the exam," take note! If your professor provides a PowerPoint, fill in the presentation with extra details. It is unlikely she will give you all the information upfront. Taking notes by hand is actually better for memory retention than taking notes on a laptop. If you have time, take notes by hand and later type them. Draw your own versions of graphs. When your professor draws a graph to illustrate a concept on the blackboard, draw your own version. Even if she gives you a print out, practice drawing and labeling the graph. You likely will need to reproduce this skill later. Focus on the connection between ideas that your professor is explaining or has mentioned previously. Aim to understand the logic between numbers in a mathematical problem. If you don't understand the concept, draw a question mark in your notes and ask a classmate or your TA later. You are more likely to remember what happened in class if you participate. Ask questions when you have them. Answer questions that you know. Engage in debates. Offer to draw graphs. Many classes have a participation grade but even if they don't, being an active learner will help you get better grades. Use class time to clarify misunderstandings about the material being covered rather than to ask logistical questions. For example, rather than asking "What's the reading for next week?," look at your syllabus. A good question would be, "Could you please explain how you produced that figure? I did not quite understand." When you get your exam, immediately write down any formulas, theories, or key terms that you think you might want to recall during the test. Read the entire test and pay attention to how many points are given to each section. Read all directions slowly and carefully. Then begin with questions about which you feel confident. Keep in mind requirements for your writing equipment. If you must use a pen, do so. Look to see if any questions are similar to questions you went over in class. When answering multiple choice or true or false questions, look out for words like "never, sometimes, always, or none." Be sure your answer fits an answer for whichever word is included. For essay questions, be sure to include a graph if one is asked for. Follow the directions carefully. If the prompt says to "explain" something, do so. If it asks you to draw a diagram and identify certain markers, do this as well. Write legibly and budget your time wisely.

Start simple for now, as complex molds are much harder to keep together at first. Get a piece of modeling wax and use a precision knife, Dremel, and any other tool needed to make a model of your jewelry. Whatever shape you make now will be the shape of your finished piece. You are making an exact replica of your eventual jewelry. Using a piece of jewelry you like as a model will help you design better pieces when you first start. Using some more wax, craft several long, wires out of wax and attach them to the model so that they all lead away from the piece. This is easier to understand when you see the whole process -- this wax will be covered in plaster, then melted out to make a hollow version of your shape. You then fill in the hollow part with silver. f you don't make sprues, the melted wax can't actually get out and make a hollow area. For smaller pieces, like a ring, you may only need one sprue. Larger pieces, like belt buckles, may need up to ten. All the sprues should meet at the same place. They will need to be attached to a sprue base. The sprues all meet together, and you attach the mold to the sprue base where all the sprues meet. This allows the wax to melt through the bottom of the base and leave the mold. The flask is a big cylinder that slides on top of the sprue base.

Carve a piece of hard modeling wax into your desired shape. Attach 3-4 "sprues," wax wires that will provide a channel for the wax to melt out later. Attach the mold to the sprue base using a bit of melted rubber. Put the flask on top of the sprue base, making sure you have a quarter inch between the wall of the flask and the model.
