There are different types of rosin, but the two most common are light rosin and dark rosin. Light rosin is harder, and not quite so sticky as dark rosin. It's sometimes called amber or summer rosin (for the time of year it's tapped), and it's appropriate for the higher strings, like violins and violas. Dark rosins, or winter rosins, tend to be very sticky. The stickier the rosin is, the fuller the sound will be. Select a dark rosin if you play a low-stringed, large instrument like the cello, for which a fuller sound is preferred. Boxed rosin, as its name suggests, comes in a box, which makes it less prone to cracking and breaking. It's typically only available as a light or summer rosin and is usually a lower quality than cake rosin. But its low price tag makes it a good option for beginners. While cake rosin tends to be more expensive than boxed rosin, you're getting a purer, more high-quality rosin. It comes in a variety of colors, from amber to black, so you can select the best kind for your instrument. New rosin needs to be roughened in order for it to stick to your bow. Take a piece of sandpaper, around 220-grit, and rub it all over the top of the rosin block. Stop when you see the rosin producing dust. You can also use a knife to score it and cut a crosshatch pattern into the top.

One-sentence summary -- Buy light rosin for smaller instruments. Choose dark rosin for a fuller sound for larger instruments. Select boxed rosin for a durable, low-priced option. Opt for cake rosin for a higher-quality product. Rub new rosin with fine-grit sandpaper to increase stickiness.

Q: There are many different patterns to choose from to use as a guide to make a jacket. If you are new to sewing, then try to find a pattern that is labeled as “easy” or “beginner” level. Consider the style of the jacket pattern as well. Jackets come in many different lengths and with a variety of different details. Find a pattern that suits your style and needs. If you are a beginner, then try to find a jacket pattern that does not require interfacing or a lining. This will make the process much easier. You may also want to avoid patterns with lots of pleating, special stitches, and complex closures. The pattern will include a list of necessary materials to complete your project. Use this list to ensure that you get everything you will need before you get started. Some things your pattern may recommend purchasing include:  Fabric for the outside of the jacket. Your pattern may suggest several different fabric options and you can choose the one that best suits your intentions for the jacket. For example, if you want a warm winter jacket, then a wool or corduroy fabric may be your best option, but if you want a light spring jacket, then a cotton or denim may be best.  Fabric for lining the jacket Interfacing to go in between the two layers Buttons, snaps, or a zipper Thread in a color that matches your jacket’s fabric . Before you begin sewing, it is always a good idea to read through all of the pattern’s instructions and make sure you understand what you will need to do to make your jacket. Highlight anything in the pattern instructions that is seems important, such as how to lay the fabric on the pattern pieces before cutting them out. When you are ready to sew, cut out the pattern pieces that you will need to create the jacket. Usually, patterns feature a few different designs and the different pieces are labeled with a letter, such as A, B, C, or D, to indicate which pieces go with a particular design. Check your design to find the letter of your desired design and then cut out the pieces that are labeled with this letter. If you have opted for an easy or beginner level pattern, then there should not be too many pieces to cut out. You will likely only have to cut out the pieces for the front, back, and sleeves of the jacket. Each of the pattern pieces will indicate what type of fabric you need to cut it out of and also how to align the fabric on the pattern piece. For example, some pieces will need to be made from your outer fabric, lining fabric, and interfacing, while other pieces may only need to be made from the outer fabric and/or lining. The pattern will also indicate if you need to line up the piece along a fold in the fabric or if you can cut it out anywhere on the fabric.  Place pins along the edges of the fabric only to avoid damaging the jacket fabric. If your material is especially delicate, then you may want to use binder clips or weights placed on the edges of the fabric and pattern pieces instead of pins. When you have finished pinning, cut along the edges of the pattern piece and fabric. Make sure to cut right along the edges of the lines and not inside or too far outside of them. Then, if you need to make another piece from a different type of material, pin the pattern to that fabric and cut out the next piece.
A: Choose your jacket pattern. Purchase fabric and other necessary materials. Read the pattern instructions carefully Cut out the pattern pieces. Pin the pattern pieces to your fabric. Cut the fabric along the edges of the pattern pieces.

Article: The pumpkins should be bright orange in colour (depending on the species) with a hard shell. Their stems and often the vine itself should be starting to dry out and wither. They won't keep for more than a few days before spoiling. Use a pair of shears to cut the stem, leaving it a few inches long. Don't break off the stems, since this will cause the pumpkins to rot. Keep them away from humidity, damp, and direct sunlight. They do not need refrigeration. Pumpkins keep for many months after they have been harvested. A mild chlorine rinse before storage can discourage mold and fungi. Use a mix of 1 cup (240 mL) household chlorine bleach and 5 gallons (18.9 L) cold water.
Question: What is a summary of what this article is about?
Check to see if the pumpkins are ready. Don't harvest pumpkins that are still soft. Cut the pumpkins' stems. Store the pumpkins in a cool, dry place.

Article: Make the top triangle slightly smaller than the bottom one. However, instead of drawing a triangle on bottom, draw an oval. Also add a vertical line on the right side. Also add a parallelogram on the left side of the drawing, and various small shapes to create legs. Give shape to the head and wings as shown. Add facial features.
Question: What is a summary of what this article is about?
Draw two guidelines that intersect. Draw sloped triangles at the left end of each line. Repeat the previous step for the right end of each line. Draw a ring around the oval from the previous step. Begin connecting the shapes. Continue making connections. Erase the guidelines. Color the drawing. Finished.
