Q: The semicircle needs to be twice as wide as you want your final hat to be. Something around 6 to 8 inches (15 to 20 cm) would be ideal; this will give you a cute hat that's about 3 to 4 inches (7.6 to 10.2 cm) tall.  Alternatively, use a bowl or plate to trace a full circle. Cut the circle out, then cut the circle in half. Use red sparkly felt for a fancier touch! Wrap a measuring tape around the base of your cone to get the circumference, then cut a strip of white fur according to that measurement. Make the fur strip about 1⁄2 to 1 inch (1.3 to 2.5 cm) wide.  You can find white fur in the kids' crafting section of a craft store. If the fur is too long, cut it shorter with scissors. If you can't find white fur, you can use white felt instead.
A: Draw a semicircle on a sheet of red felt and cut it out. Cut a strip of white faux fur for the brim of your hat. Finished!

Article: Though they may develop in the course of a few days, some symptoms of Lyme disease may take months to develop.  Severe headaches, stiffness in your neck, or arthritis-like pain in your joints may indicate an untreated infection.  See a doctor immediately if you're experiencing any persistent stiffness, particularly in your knees, shoulders, elbows, or ankles.  Muscle, bone, joint, and tendon pain from a Lyme disease infection may be intermittent. Numbness, or tingling in the hands and feet are also cause for concern. Bell’s palsy is a condition in which the muscles on your face lose definition or begin to droop, and may be caused by Lyme disease. In fact, any issues with your facial muscles may indicate a Lyme disease infection.  If any part of your face becomes weaker, or it seems as though you’ve lost control of muscles on any part of your face, see a doctor as soon as possible. Lyme carditis is a rare condition that occurs as a symptom of Lyme disease and affects the regularity of your heart beat.  Watch out for heart palpitations or any irregularity in your heart beat, including sudden, drastic changes in heart rate.  Dizziness and shortness of breath may also indicate Lyme carditis.  See a doctor as soon as possible if you're experiencing any of these symptoms. Note that these and many other symptoms related to a Lyme disease infection may come and go, or even disappear without treatment.  The infection, however, may still be present, and will require treatment to prevent any further health complications. The important neurological issues to watch out for include numbness, cognitive problems, and shooting pains. These may indicate inflammation of the brain or spinal cord, and need to be addressed immediately.  Shooting pains in any part of your body that occur at night are a readily recognizable sign of neurological issues. Numbness or tingling sensations in your extremities may also indicate potential neurological issues caused by Lyme disease. Any cognitive issues you notice, even simply changes in your short-term memory, may also indicate neurological complications. If initial symptoms are mild, you may not notice a Lyme disease infection for years. Weakness, especially weakness associated with severe fatigue is a cause for concern, as is any partial or complete loss of short-term memory.  Further, if any of the following symptoms also occur, especially in combination, you should see a doctor immediately:  Heightened sensitivity to light or sound. A noticeable loss of appetite. Pain that moves around your body, or pain behind your eyes. Any loss of feeling or recurring numbness in the extremities. Trouble swallowing. Depression or seizures. Hepatitis of other liver complications.

Article: Give yourself enough time in the morning to dress, shave, and apply makeup. If you need to, wake up 15 to 30 minutes early to make sure you are dressed and groomed before stepping out the door. This way you can avoid having to do these things while driving. If you don’t have enough time in the morning to finish getting ready, then bring your grooming supplies with you in the car. Wait until you arrive at your destination and your car is parked before finishing your grooming routine. Before you start the car, make sure to store loose objects that can roll around and distract you while you are driving. Place them in the trunk, a secure bag, or in your glove compartment. This way you can avoid reaching for these objects in the car if they get loose, which can be dangerous. For example, place grooming supplies, clothes and shoes, books, and bags in the trunk or glove compartment. While sitting in your parked car, confirm and familiarize yourself with the route you will be taking. Also, check the traffic report while you are confirming your route. This way, you can avoid having to re-route your GPS while driving. If you are using a GPS, make sure it is set up before you begin driving, and use the voice function so you do not have to glance at your GPS. Make sure to adjust the climate controls to the correct setting. Also set your radio to the station you want to listen to and adjust the volume while your car is parked. Additionally, make sure to adjust your mirrors, seat, and steering wheel to the correct positions beforehand. Before you take off, make sure your children are fastened in their car seats or seatbelts. Also, make sure your pets are in a cage and the cage is secured with a seatbelt. By doing this, you can avoid having to reach back to adjust your child’s car seat, or your pet’s cage while you are driving. When driving with animals in the car, always make sure they are secured in a cage.
