In one sentence, describe what the following article is about: Play starts with the player on the dealer's left and goes clockwise around the table. If you don't like what you see on the discard pile, start your turn by taking the top card off the draw pile. Add the card to your hand and look for possible scoring opportunities. If you draw a red 3, play it and pick another card. Then, continue your turn as you normally would. You have to pick up a card at the start of your turn unless you're taking from the discard pile. At the start of your turn, you have the choice to choose from either pile. It's one or the other. If the top card on the discard pile catches your eye, take it instead of picking from the draw pile. It can only be taken if you are able to use it right away to score points. Keep in mind, however, that you have to take the entire discard pile along with it! The discard pile is one of the most exciting parts of canasta. By taking the discard pile, you might end up with a lot extra cards to deal with, but you also get many more potential scoring opportunities. After opening your turn, search your hand for cards you can lay face up in front of you for points. Melding in canasta basically means matching same-rank cards, possibly with some wildcards as well. The initial meld in your hand needs to be worth at least 50 points before you play it. Once you play that first meld, you can play whatever combinations you see fit during the round. The initial meld requirement increases as the game goes on. Once you accumulate 1,500 points, your meld has to be worth at least 90 points. At 3,000 points, it needs to be worth 120 points. If you happen to have a negative amount of points at the beginning of a round, your initial meld only has to be worth 15 points. Remember that each meld must have at least 2 natural cards to be played. You can add to existing melds you or your partner start, but you can't add to an opponent's meld. No matter what you do during your turn, end it by getting rid of one of your cards. Place it face up so the next player can think about taking it during their turn. Keep the discard pile square so nobody can see the cards underneath the one you laid down. Try to get rid of less valuable cards and ones you don't think you can use to score points. It takes a little bit of strategy, so do your best to keep track of the cards on the table. If someone used most of the 4s to make a meld, for instance, the one you're holding isn't very useful. Meld your remaining cards or meld and discard to "go out." When you go out, you don't get to play until the next round begins with a fresh hand, so pick your chances with caution! Going out isn't always the best move, especially when you're playing with a partner. For instance, you could choose to extend the game so you can make more matches. Your partner might also have high-value cards that would go to waste. If you are able to go out in a single hand, you get a 200 point bonus instead of 100. It is very hard to do, so you won't see it happen too often.
Summary: Pick from the draw pile at the start of your turn if you need another card. Take the discard pile if you are able to make a match with the top card. Begin melding cards into sets of 3 or more during your turn. Discard a card face up at the end of your turn. Go out by using up all the cards in your hand.

In one sentence, describe what the following article is about: Thread your needle with matching, lightweight thread, and sew straight across your hem roughly 1/4 inch (6 mm) away from the raw edge. After sewing this line, trim the edge so that there is only 1/8 inch (3 mm) between the thread line and the raw edge. This stitch will end up being on the bottom of your hem. It should help you maintain an even, consistent roll. Fold the raw edge toward the wrong side of the fabric and press in place using an iron. While not entirely necessary, pressing the fold in place will make the hem less likely to unroll as you stitch. Fold the fabric so that the bend falls just past your initial row of stitching. You should see your initial stitching along the underside of the fabric but not from the front. Pick up one thread from the fabric and a small stitch from the edge of your fold. Pull the needle through, but do not pull it taut just yet. Use a small, sharp needle for best results. Doing so will make it easier to pick up single threads along your hem. The stitch made into your fold should be as close to the actual fold as possible. Position it in between your initial line of stitching and the fold itself. The threads you pick up from the front of the actual fabric should be directly above the stitch made into your fold. These threads should also be right above the raw edge. Make sure that you only pick up one or two threads from the fabric. Picking up more will cause the hem to be more visible from the front of the fabric. Each stitch should only pick up one or two threads from the fabric, and the stitches should be spaced roughly 1/4 inch (6 mm) apart. Repeat this until you have 1 to 2 inches (2.5 to 5 cm) of hem stitching. Lightly pull on the thread in the direction of your stitching. The raw edge should roll itself down into your hem, disappearing from sight. Use firm pressure, but do not pull tightly. Pulling too tightly can cause the fabric to bunch up. Smooth out any bubbles or bumps with your fingers. Continue stitching along the rest of the hem in the same manner until you reach the end. Knot off the end and cut off any excess thread. As you get better at the process, you can pull the thread after 4 to 5 inches (10 to 13 cm) of stitching rather than every 1 to 2 inches (2.5 to 5 cm). If completed correctly, the raw edge should be hidden along the wrong side of the fabric and the hem stitching should be barely visible from the front. The hem may already be smooth enough, but if desired, use an iron to press it further. This step completes the process.
Summary:
Sew straight across the raw edge. Fold in the raw edge. Pick up a few threads with your sewing needle. Make a few more stitches in the same manner. Pull the thread through. Repeat along the length of the hem. Iron press when finished.
