In one sentence, describe what the following article is about: Making a sound on a trumpet requires more than just blowing air into it. Use the proper lip technique for the best tone. Start by saying the letter M, and holding your lips together right when they touch each other. Then tighten the corners of your mouth. This is the starting mouth position for trumpet playing.  Don’t pucker your lips. Keep your mouth straight across. Keep your jaw loose and don’t clench your teeth. This buzzing produces the trumpet sound. Use your diaphragm and push air through your lips while keeping them clenched. Produce a buzzing sound as your lips vibrate.  Imagine the noise you’d make if you were imitating a mosquito buzzing. This is the sound you want. Don’t change your lip position like you would when you blow air out. Keep your lips together so they vibrate and buzz. Avoid puffing out your cheeks. Lick your lips first if you’re having trouble getting this sound. It won’t work as well with dry lips. When you’ve gotten comfortable buzzing your lips, get a feel for blowing into the trumpet mouthpiece. Take the mouthpiece and press it against your lips gently. Maintain the same mouth position as before. Then buzz your lips into the mouthpiece.  The mouthpiece won't produce much sound by itself, so don't worry if notes don't sound good yet. The mouthpiece detaches easily. Just twist it loose a bit while pulling gently and it will come right out. Do the same to put it back in. Don't hit it in or it may get stuck.
Summary: Press your lips together and keep the corners of your mouth tight. Push air through your lips to make a buzzing sound. Blow into the mouthpiece when it’s not in the trumpet.

Q: There are two canning techniques.  One uses a pressure canner, a device that subjects canned food to high pressures to create high temperatures.  The other method is to use a boiling-water canner, a device in which canned food is submerged in boiling water. When canning meat, seafood, poultry, and vegetables, pressure canning is the only canning method recognized as safe by the USDA. In addition to a canning device, canning at home requires a glass jar (a Mason jar, typically) and, of course, the food that you wish to can.  If you grow your own produce, you could save even more money on your canning materials.  You can often assemble canning materials – including a canning machine – for free on digital marketplaces like Craigslist. Try to get a set of canning jars for free or at a discount rate (but be sure to sterilize them by boiling them in water before use). If you have a community garden in your area, you might be able to lease a small plot for yourself to grow the veggies you want to can. There are two standard canning methods.  One is known as “hot packing.”  This involves blanching your food (usually vegetables), then loading it tightly into canning jars along with some of the water they were blanched in.  The other is known as “raw packing.”  This involves placing raw food into a canning jar and pouring very hot water over it.  If you have a boiling-water canner, you should raw-pack your canned food.  If you have a pressure canner, you should hot-pack your canned food. After hot packing, seal the jar with a metal lid, and follow the directions that came with your canning device to determine your next steps.  The amount of time your canned food will need to spend in the canning device depends on how much you have and what sort of food it is. The only additional cost when canning is your time.  Pressure canners work faster than boiling-water canners. Once you’ve canned your own foods, you’ll need to assign each can an expiration date so that it can be incorporated into your pantry system.  Generally, home-canned food is best eaten within one year.
A: Choose your method. Assemble your materials. Can your food. Determine expiration dates.

Problem: Article: If the pattern includes a lining, then it will indicate how much of the lining fabric you need to purchase. Buy this amount of fabric. If not, then purchase the same amount of lining fabric as you needed for the skirt. Good lining fabrics include rayon, satin, and smooth cotton, but you can use anything you like as long as it won’t cling to the skirt fabric or tights.  If you needed 2 yd (1.8 m) of fabric for the skirt’s exterior fabric, then you will need 2 yd (1.8 m) for the lining as well. If you want to line a pre-made skirt, measure the circumference of the widest part of the skirt and the length of the skirt. Add 6 in (15 cm) to this length and buy that amount of fabric. Keep in mind that you will have to rip the seams on the skirt and re-sew it to add a lining properly, so this is not recommended. If you don’t pre-wash your lining fabric, then it might shrink after the first time you wash the garment and this could distort your finished skirt. Wash and dry the fabric according to its care instructions. This will vary depending on the type of fabric.  For example, if you have chosen a silk fabric for the lining, then you might need to hand wash it and allow it to air dry. For specialty fabrics, you might even need to have the fabric dry cleaned. Pin the pattern pieces onto your lining fabric and then cut them out with a sharp pair of fabric scissors. Make sure to mark the lining material with all of the same darts, notches, and other special markings as the pattern indicates. Your lining pieces need to be exactly the same size and shape as your skirt’s pieces. However, if your skirt includes special details, such as pockets, then you can leave these out. If your skirt’s lining piece is already in 1 piece, then you won’t need to sew it together. However, if there are multiple pieces you need to connect, then pin and sew these together as indicated by your pattern. If the skirt includes a zipper, then you will need to add it to the outer layer of the skirt at this time as well. the seams before you secure the lining and skirt together. If you sewed multiple pieces of fabric together for your skirt’s lining, then you may want to iron the seams on the lining. This will ensure that the seams lay flat and improve the look of your finished skirt. Lay the fabric so that the wrong sides are facing up and then use your fingers to gently separate the seams. Then, run the iron along the open seams to make them lay flat. If your fabric is delicate, such as silk or satin, then use the lowest setting on your iron and lay a towel over the fabric before you iron it.
Summary:
Choose lining fabric that is lightweight and smooth. Pre-wash the fabric to shrink it. Cut the same pattern pieces you used for the exterior of the skirt. Sew the pieces together as indicated by your pattern. Iron
