In one sentence, describe what the following article is about: There are many beautiful sewing patterns available for making a ballgown. Take some time to visit your local craft store and look through the pattern catalogs. Consider the styles that suit your body type best to help you narrow down your choices. Then, purchase the pattern that suits your style for the ballgown. Sewing patterns require varying degrees of skill to use. Consider your level of sewing expertise as you consider patterns. For example, if you are a beginner sewer, then stick to patterns that are labeled as “beginner” or “easy.” If you are an experienced sewer, then look for patterns labeled as “intermediate” or “advanced.” When using a pattern, it is important to use measurements to determine what size you need to make your ballgown in rather than relying on the size you normally wear. Measure around your bust, natural waist, and the widest part of your hips. Then, check the chart on your pattern to determine what size you will need to make your ballgown. Your ballgown will probably require a large amount of fabric since most ball gowns have long, flowing skirts. Check your pattern’s package to determine how much fabric you will need to buy. Depending on the style of your ballgown, you may need more or less fabric. The required amount of fabric should be indicated on the back of the pattern’s package.  When you are working on a sewing project, it is always better to buy more fabric than you think you will need. Consider rounding up the patterns suggested fabric amounts to the nearest whole amount. For example, if the pattern recommends 2 ¾ yards of a specific type of fabric, then you might want to round up to 3 yards. Consider your pattern’s recommendations for fabric type when you are selecting a fabric.   For example, if the pattern recommends using a lightweight fabric, such as satin or crepe, then stick to these types. Subbing for a heavier fabric may affect the way the dress hangs and moves. Check the pattern’s indications for what you will need to execute the design. Along with fabric, your pattern may also require you to buy interfacing, a zipper, hook and eye closures, ribbon, or other notions.  Make a list of everything you will need and purchase these items before you begin working on your ballgown.
Summary: Select a pattern that matches your skill set. Take your measurements. Buy your fabric. Buy your notions.

To find the greatest common factor (GCF) between two or more numbers, you need to start by breaking down each number into its prime number factors. You can use the factor tree method to do this.  You will need to create a separate factor tree for each number. The process required for making a factor tree is the same as described in the “Making a Factor Tree” section. The GCF between two or more numbers is the largest prime number factor that is shared between all of the given numbers in the problem. This number must divide evenly into all of the original numbers in the problem.  Example: Find the GCF of 195 and 260.  ......195 ....../....\ ....5....39 ........./....\ .......3.....13 The prime factors of 195 are: 3, 5, 13 .......260 ......./.....\ ....10.....26 .../...\ …/..\ .2....5...2...13 The prime factors of 260 are: 2, 2, 5, 13 Look at all of the factor trees created for your original values. Identify the prime factors of each original number, then highlight or write down all of the factor numbers that both lists have in common  If there are no common factors between the numbers, the GCF is the number 1.  Example: As noted previously, the factors of 195 are 3, 5, and 13; the factors of 260 are 2, 2, 5, and 13. The common factors between both numbers are 5 and 13. When two or more numbers have more than one common factor between them, you must find the GCF by multiplying all of the shared factors together.  If there is only one shared factor between two or more numbers, however, the GCF is simply that single shared factor.  Example: The common factors between 195 and 260 are 5 and 13. The product of 5 multiplied by 13 is 65. 5 * 13 = 65 The problem is now complete, and you should have your answer ready.  You can double-check your work, if desired, by dividing each of your original numbers by the GCF you calculated. If the GCF goes into each number evenly, the solution should be accurate.  Example: The greatest common factor (GCF) of 195 and 260 is 65.  195 / 65 = 3 260 / 65 = 4

Problem: Article: Most achy backs caused by overwork or minor accidents (such as slip and falls) resolve on their own with a few days or so. As such, if the pain isn't severe, have some patience and the likelihood of your backache going away is actually pretty good with or without any kind of treatment.  Severe pain combined with numbness or tingling in the legs is often a sign of a serious back injury. It's important to seek professional help if your back pain also involves trouble urinating, fever or unintentional weight loss. If you develop back pain that won't go away after a few days of taking it easy, then schedule an appointment with your family physician. Your doctor will examine your back (spine) and ask questions about your family history, diet and lifestyle, and maybe even take X-rays or send you for a blood test (to rule out rheumatoid arthritis or a spinal infection). However, your family doctor is not a musculoskeletal or spinal specialist, so you may need a referral to another doctor with more specialized training. Your family doctor may recommend over-the-counter anti-inflammatories such as ibuprofen, or analgesics (pain killers) such as acetaminophen to help you cope with your backache. Consider seeing a specialist if your backache is not relieved by rest and medications. Mechanical low back pain is not considered a serious medical condition, although it can be very painful and debilitating, causing you to miss work or athletic activities. Typical causes include muscle strains, spinal joint sprains, spinal nerve irritation and spinal disc degeneration. However, medical specialists such as an orthopedist, neurologist or rheumatologist may be needed to rule out the most serious causes such as infection (osteomyelitis), cancer, osteoporosis, spinal fracture, herniated disc, kidney disease or rheumatoid arthritis.  X-rays, bone scans, MRI, CT scan and ultrasound are modalities that specialists may use to help diagnose your backache. The low back, or lumbar region, is more susceptible to injury and pain because it supports the weight of the upper body. Make sure you get the doctor to clearly explain the diagnosis, especially the cause (if possible), and provide you with various treatment options for your condition. Only the most serious causes of back pain require surgical intervention, which is quite rare. Sometimes mild backaches resolve on their own within a few days, but for more debilitating back pain, treatment is recommended because it will likely reduce the duration of the pain and lower the risk of a recurrent (chronic) problem.  Pain from mechanical back pain can be severe, but it doesn't involve high fevers, rapid weight loss, bladder / bowel problems or loss of leg function, which are all signs of something more serious. Common causes of backache include poor posture, improper lifting technique, obesity, sedentary lifestyle and mild trauma from athletic activities.
Summary:
Give it time. Schedule an appointment with your doctor. Get a referral to a specialist. Understand the cause of your backache.
