Before you begin joining your stitches, make sure to check the position all the way around your circular or double-pointed needles. Make sure that all of the cast on stitches are pointing down and that they are not twisted. If you notice any twisted stitches, straighten them out using your fingers. Joining the first and last stitches you cast on in a round is just a matter of knitting or purling. Start by inserting your needle (knit-wise or purl-wise as required for your project) into the first stitch that you cast on. This will be the stitch that has a tail of yarn extending from it. Loop the yarn over the needle that you just inserted into the stitch. Then, pull this yarn through the stitch to create a new loop. Slip the cast on stitch off of your left needle as the new stitch you just created replaces it on your right needle. Then, continue to knit or purl the rest of the stitches in the round as needed for your project.

It's either this, or lick the spoon gently. Don't drench it! It can basically be placed anywhere on your nose, as long as it is on the ledge of it. Your spoon is balanced perfectly on your nose (if you did it right)!

Open the oven with care. If you don't want to completely remove it from the oven, you can also pull the rack out just enough to access the baked food. If there is any wet batter or crumbs clinging to the toothpick, the cake or bread is not ready yet. If nothing sticks to the toothpick, the cake is ready to be taken out of the oven.

One-sentence summary -- Put on oven mitts to protect your hands properly. Remove the cake or bread from the oven. Insert a single, clean (unused) toothpick into the center of the cake or bread until it is almost all the way in. Pull the toothpick back out of the cake or bread by pulling directly up at the same angle at which you inserted it. Examine the toothpick. If the toothpick came out wet, put the cake or bread back in the oven and perform the toothpick test again in another five minutes.

To find a vet that works with frogs, contact local veterinary schools or look online for lists of veterinarians that work with amphibians. For example, you can look at the website of the Association of Reptilian and Amphibian Veterinarians. If there are several vets in your area who work with amphibians, make sure the vet you choose is the one that has the most experience with tree frogs. It's a good idea to find a vet before your frog is actually sick. Having an established relationship with a veterinarian that treats tree frogs will make it easier to get your pet quick care when it needs it. It is best to have your frog checked out by a veterinarian if you see a symptom of illness. While you may end up bringing your pet in for a problem that is non-existent, it is better to be safe than sorry. Some diseases require quick treatment in order to be eliminated. If you suspect that your tree frog is sick but you are unsure about bringing it in to be seen by a vet, at least call the veterinary office and talk to them. Tell them about your pet's symptoms and ask them if they think your frog needs treatment. If your tree frog is indeed ill, your veterinarian will begin its treatment and will give you instructions on how to continue treatment at home. Follow these directions and be sure to continue treatment for as long as your veterinarian suggests, even if your tree frog seems completely healed. If treatment is not minimizing your frog's symptoms or they are getting worse, contact your vet once again. It may be that your frog needs a different type or amount of treatment.
