Having reference pictures can be helpful when following pattern or learning a new stitch, but many of the tutorials you will find are made for right-handed crocheters. However, there are lots of left-handed picture and video tutorials available, so seek them out. Check out blogs and videos made by other left handed crocheters. You might even consider getting yourself a left handed crocheter pattern book. Crocheting left-handed does not mean that you can't use the same patterns as right-handed crocheters. Follow the pattern instructions exactly as they are written. Just use your left hand to crochet the stitches. One of the difficult parts of using tutorials when you are a left-handed crocheter is that the images usually show a right-handed crocheter. One way to change the image into something you can try to do with your left hand is to save the images and then flip them horizontally. This will reverse the image so that it looks like the crocheter is left handed.

One-sentence summary -- Seek out left-handed tutorials. Follow the pattern as usual. Take pictures of images and flip them.

Q: Trying to cross-breed rose bushes to obtain a new variety is not for the faint-hearted. This may be something best left to commercial nurseries that have huge resources at their disposal as it can take many thousands of attempts over many years to obtain a new variety. If you want to try creating a new variety of purple roses, you will need to cross-pollinate two 'parent' plants. This means taking the pollen from one rose plant and applying it to the stigma of another plant in the hope the two plants will breed together to create an offspring ('hybrid') with some of the preferred characteristics of the parents. Late spring is the time to cross-pollinate roses. It should be done on a day when rain is not expected. Select two plants you want to try crossing. Remove the petals from a bloom on the plant you have chosen to bear the seed of the new hybrid. Remove the anthers from the plant to prevent it from self-pollinating. Using a paintbrush, remove pollen from one parent and apply to the stigma of the other. It's a good idea to label the flower you have just pollinated with details of which plant it is crossed with and the date, for your future reference. Wait for hips to develop on your cross-pollinated rose bush. After four months harvest the seeds and plant them, using the method in Method 2 above. If you are lucky, these seeds will develop into purple roses.
A: Understand that cross-breeding roses is a difficult task. Cross-pollinate two "parent" plants. Attempt to cross-pollinate the roses in late spring. Learn how the cross-pollination process works. Wait for hips to develop, then plant the seeds.

Article: Look at the ten cards in your hand. Sort them into any possible "melds," which are sets or runs. A set is three or four cards of the same rank (5-5-5), and a run is three or more cards of consecutive rank in the same suit (4-5-6). An example of a set is 10 of diamonds, 10 of spades, and 10 of clubs. An example of a run is jack of diamonds, queen of diamonds, and king of diamonds. Since aces are low, they can't be in a run with a king. You can have ace-2-3, but not queen-king-ace. If you weren't the dealer, you get to decide if you want to pick up the face-up card in the discard pile, or if you want to pass on it because it's not a helpful card for you. If you pass, the dealer can choose to pick it up. If you both decline it, the non-dealer picks up the card from the top of the stock pile. Whether you go for the card in the discard pile or the one on top of the stock pile, pick up your new card and assess whether it will help you form any melds. Look to see if you already have a couple of cards with the same numerical value, or if it suddenly connects a couple cards to form a run. If you're picking up a card from the stock pile, don't let your opponent see what it is unless you're immediately placing it into the discard pile. Select a card from your hand that probably won't be helpful and place it face-up in the discard pile. If a card seems like an outlier that won't match easily with your other cards, then it might be worth discarding. You can also discard whatever you just picked up from the stock pile. You can't discard a card you just picked up from the discard pile in that turn. You can discard it during your next turn if you want, but you must keep it for at least one turn. At the end of every turn you should still have ten cards. Go back and forth drawing cards with your opponent and attempting to form melds with all your cards. At each turn, decide if you want the card that your opponent just placed face-up in the discard pile, or if you want to take the mystery card from the top of the stock pile. As you form melds, do not place them on the table. You don't want your opponent to see your progress. If a player takes the third to last card in the stock pile and the game is still going, then the hand is cancelled. No points are awarded to either player, and the cards must be re-dealt.
Question: What is a summary of what this article is about?
Sort your cards into melds. Choose whether to take the card in the discard pile. Pick up a new card. Discard a card you don't want. Take turns picking up cards and discarding cards. End the game if only two stock cards remain.

Article: Be careful when you mix these substances; doing so will cause the solution to get very hot. You'll need enough of the solution to cover the charcoal completely. For normal-sized batches of charcoal, 100 g (3.5 oz) of chloride mixed with 1.3 cups (310ml) of water should be enough. Calcium chloride can be bought at most hardware stores, home centers, and general retailers. If you can't find calcium chloride, you can substitute it for bleach or lemon juice. Just use either 1.3 cups (310ml) of bleach or 1.3 cups (310ml) of lemon juice instead of the calcium chloride solution. Transfer the dry charcoal powder to a stainless steel or glass mixing bowl. Add the calcium chloride solution (or the lemon juice or the bleach) to the powder in small increments, stirring it with a spoon as you do so. When the mixture reaches paste consistency, stop adding the solution. Cover the bowl and allow it to sit untouched. After that, drain as much of the remaining moisture from the bowl as possible. At this point, the charcoal should be wet, but not saturated. Return your charcoal to the (cleaned) metal pot and put it back on a fire. The fire will need to be hot enough to boil water for the charcoal to activate. After cooking for 3 hours at this temperature, the charcoal will be activated.

Combine calcium chloride and water in a 1:3 ratio. Use bleach or lemon juice as an alternative to the calcium chloride solution. Stir together the calcium chloride solution and charcoal powder. Cover the bowl and let the charcoal sit for 24 hours. Cook the charcoal for another 3 hours to activate it.
