Q: The best way to heat treat a blade is using a forge. For smaller blades, a torch can work as a substitute. For a forge, either a coal or gas forge will work. Prepare your hardening bath. To cool the knife, you will need to douse it in a hardening bath. What you use depends on the type of steel, but for 01 you can use a bucket of motor oil. You need to be able to completely submerge the blade in the bucket. Keep it heating until the metal is orange. Tap it against a magnet to see if it is hot enough. When the steel reaches the correct temperature, it loses its magnetic properties. Once it does not stick, let it cool by air. Repeat this process 3 times. On the 4th time, instead of letting it air cool, douse it in the oil bath. Be aware that there will be fire when the blade is put into the oil, so be sure that you are properly protected. When the blade is hardened, it can break when dropped, so handle carefully. Set your oven for 425. Put the blade on the middle rack and cook it for 1 hour. Once that hour is up, heat treatment is complete. Use increasingly finer grits of paper, going past 220 and up to around 400 grit. Polish the blade if you want some extra shine.
A: Prepare the forge. Heat the blade. Preheat your oven. Sand the blade again.

Q: Set the pieces next to each other, so the edges you want to sew together are touching. The knits should be facing right side up. Pull out yarn from the skein you used to knit the pieces. Measure the length of the knit pieces you'll be stitching together and pull out 3 times that length. Cut the yarn and thread it through a blunt needle so that 4 inches (10 cm) are pulled through the eye to keep the yarn in place. For example, if you'll need to sew a 5-inch (12-cm) length, thread a 15-inch (36-cm) strand of yarn onto the needle. Tie a knot at the bottom of the yarn tail so it's secure when you pull the yarn through the bottom of the left piece. Use a slip knot or whatever knot you're comfortable with making to securely tie it to the piece. The needle should go from back to front into the first stitch of the piece that you're joining. Pull the yarn through. You don't need to pull the yarn tightly to keep the 2 knit pieces touching, since you'll tighten them later. The 2 knit pieces can be up to 1-inch (2.5-cm) apart while you're doing the mattress (invisible) stitch. Pull the edge of the left piece to reveal a gap with horizontal bars. This gap will be between the edge and second-to-last row you knitted. Insert the needle below 2 of the horizontal bars near the bottom of the piece and pull the yarn up and through. Avoid pulling the yarn tightly to bring the 2 knit pieces closely together. For a tighter seam, you could insert the needle under 1 of the horizontal bars instead of 2. Stay consistent when you go back and forth between the 2 knit pieces. Pull the edge of the right piece so you can find the gap with the horizontal stitches. Insert the needle under the bottom 2 horizontal bars and pull the yarn through. The yarn should create a line that's even with the stitch you pulled through on the left piece. Insert the needle back into the left knit piece. Again, go under 2 horizontal bars and pull the yarn through. Then, insert the needle back into the right piece of fabric. Continue to sew until you've mattress stitched about 2 inches (5 cm). Use one hand to press down on the 2 knit pieces and use your other hand to hold the yarn. Gently pull the yarn away from you so it tightens the mattress stitches you did. You should see the knit pieces join together and the mattress stitch won't be visible. Avoid pulling tightly or you'll make the pieces bunch together. Pull just until the pieces are touching. Keep inserting the needle below 2 horizontal bars and pulling the yarn through. Do this back and forth on both pieces until you've done another 2 inches (5 cm). Pull the yarn to tighten the mattress stitch. Keep doing this until you reach the end of the seam. Once you've joined the 2 pieces together, insert the needle into the loop on the opposite piece. Pull the yarn through the loop so it tightens. Cut the yarn to leave a 2 inch (5 cm) tail and weave the end through your knit piece. The mattress stitch will make a tight, straight seam that's good for joining sleeves or shoulders.
A: Arrange the 2 pieces of knitting. Thread the yarn on a blunt darning needle. Attach the end of the yarn to the bottom corner of the left piece. Insert the needle into the bottom corner of the right piece. Find the gap next to your stitch edge and insert the darning needle. Insert the needle into the right knit piece and pull the yarn through. Alternate the mattress stitch between the left and right pieces of fabric. Pull the yarn to bring the 2 knit pieces together. Continue to mattress stitch in 2 inch (5 cm) increments. Tie off the yarn at the end of the seam.

Q: Not getting enough sleep can affect your concentration and cause memory problems, hindering your learning process. A healthy sleep schedule should be kept up as lost sleep has a cumulative effect on your mind and body. As a general rule, the required amount of sleep for optimal functioning is: 9-11 hours a day for children 8.5-9.5 hours a day for teenagers 7-9 hours a day for adults As a general rule, eating healthy will improve your overall well-being, both mentally and physically. Improve your capacity to learn by consuming healthy, "smart" foods that aid with concentration. Make sure to eat a well-balanced breakfast every day, avoid high fat foods, and try to add learning-friendly foods to your diet, such as: Omega 3-rich fish (e.g. salmon) Whole grains Avocados Blueberries Dark chocolate Regular exercise is a key component to concentration and learning potential. If possible, exercise right before studying, which will raise your focus for 2-3 hours. If your concentration starts to fade while reading or studying, take a 15 minute exercise break to renew your energy (e.g. a quick walk around the block). Exercise also releases endorphins and serotonin, which boost mood and fight depression. You don't have to bust out the weights or sports equipment. A brisk walk or jog around the block will do. Get the best learning experience possible by keeping an open line of communication with your teachers. Ask questions at appropriate times (e.g. after class), visit during office hours, and follow-up by email to confirm that you have absorbed what they told you. Reaching out will let a teacher know that you appreciate their time and wisdom, and that you should be taken seriously. Setting clear goals for your learning process will keep you motivated and organized. Be realistic about your goals in terms of time and complexity. For example, if you want to learn the theoretical component of how to drive, aim to read and retain one chapter of the driving manual per week.
A: Get enough sleep. Eat a healthy diet. Exercise regularly. Communicate with your teachers. Set goals.

Q: On December 28th, also known as Holy Innocents' Day, many people play jokes on others. It's equivalent to April Fools Day in the United States. On top of playing pranks on one another, many cities have their own special festivals. Visit Jalance for the Fiesta de los Locos, or Crazy People's Dance. Ibi holds a Flour Battle, or Els Enfarinats Festival throughout the day. Celebrated on January 5th, towns across the country hold parties and parades to commemorate the arrival of the Three Kings the following day. Spend the night in Madrid or Barcelona to see parades with massive floats. Children expect larger gifts from the Three Kings overnight, so they often leave their shoes on windowsills or balconies to be filled with presents. Children wake up on January 6th and open the presents that the Three Kings brought them. Exchange gifts throughout the day. Afterward, have a large feast to celebrate. Enjoy a Roscon de Reyes, a ring-shaped fruit cake with a figurine baked inside. Whoever finds the figurine becomes the king of the day!
A:
Play pranks on one another on Dia de Los Santos Inocentes. Go to a parade on the eve of Epiphany. Give large gifts to one another on Three Kings' Day.
