Place one end of the wooden board vertically against the clamp backing on the opposite side of the jig, then pull the lever to press the clamp tight against it. Test the board to make sure that it doesn’t slide around. The clamp lever should lock into position once the clamp is fully extended. The guide holes should be just large enough to comfortably accommodate the drill bit. Most standard Kreg Jig models will have at least three guide holes so that you can drill as many holes as needed to support the joint.  For greater precision and security, keep your pocket holes spaced at even distances. Should you need more pocket holes than your jig allows, you can make room for more by shifting the wood down in the clamp after drilling your first set. Begin drilling into the guide holes using steady pressure until you’re stopped by the depth collar. Pull back on the drill as you work to free the guide holes of loose wood chips. Drill as many holes as you need to create a strong joint that will suit the purposes of your project, then turn the board around and repeat the process on the other end.  Try drilling on a scrap piece of wood first to confirm that the settings on the jig are correct. You’ll need to drill at least two pocket holes—otherwise, the boards will pivot around the single screw.  The jig will allow you to drill at a shallow angle into the wood, which results in a more structurally sound joint than if you were to drill straight through.

Silkscreens can only apply one color at a time, so create a simple shape or outline to begin learning. Whatever you draw will eventually be the inked part of the print. To make your own print, you need:  Poster board, thin cardboard, or other thick & sturdy paper. Pencil X-acto knife or another precision knife Screen printing isn't difficult, as what you draw is exactly what you get on the final print. However, there are certain principles and limitations to screen printing that you should know as you design your print:  You can only print 1 color at a time. High contrast images (like black on white) work the best, as you cannot use shading. For complex designs, you need to make multiple prints, one for each color, and layer them after the ink has dried. Sketch out the blocks of your design. You can upload photos or other images into photo editing software as well and use those. To do so, reduce the drawing to a basic two-tone outline then print it. To make a stencil on Photoshop, for example, you would take a black and white image and click Image → Adjustments → Threshold, then set it up near the highest it can be. Everything that you cut away will be un-inked on the final print, and everything covered by the stencil will be covered in ink. For example, imagine you are printing the red logo of a bulls-eye on a white t-shirt. When you cut out the stencil, all of the rings that you cut away will be white, and all of the rings that are covered by the stencil will be red. For complex prints, it can be very difficult to cut out the entire outline. In this case, use thick black ink on transparent paper to make your stencil. Your stencil or drawing needs to block light, as this is what etches the design into the screen and allows you to print. Everything covered by a stencil or black ink will not get exposed to light, leaving it "open" and allowing ink to pass onto the shirt or item.

Goldfish require particularly roomy living arrangements in order to stay healthy. While they are pretty small fish, they need larger tanks than you might expect.  You can do better than a bowl.  Despite the beauty of a goldfish suspended in a sphere of glass, most fishbowls simply don’t provide enough room for their occupants. A single fancy goldfish can be kept in a 10 gallon (37.9 L) tank, but bigger goldfish like comets need a tank of around 50 gallons (189.3 L). If you are able to keep one goldfish from overthrowing your empire, and wish to allow them a friend with which to endure their captivity, you’re going to need to increase the capacity of your fish tank (by roughly 10 gallon (37.9 L)) for each additional fish. A 20 gallon (75.7 L) is ideal for your first goldfish, and can ultimately hold 2-3 fancy goldfish. An ideal size would be 15 gallons (57 L), but this depends on the amount of fish. Most goldfish favor a palace or castle ambiance.  Shoot for somewhere in between.  Gravel is a must, and plants are recommended.  That said, your selection of décor, gravel, and plants must follow certain guidelines:  Choose a goldfish appropriate gravel.  Don’t actually use pieces of gold, as these will likely be dangerously small.  Goldfish are scavengers.  They will pick up pieces of gravel and mess around with them just for fun. Use gravel that is made up of pieces that are too large for the fish to swallow. Definitely hook your goldfish up with ample rocks, caves, or plants.  Goldfish like to adventure, and can easily be fooled into thinking they’re not in a fish tank. Don’t use wood.  It looks spectacular, but will color your water and, depending on the type of wood, will dissolve. Be aware that some rocks and sea shells will affect the pH of the water.  If you’re adding stuff you find on the beach willy-nilly, you’re going to need to be checking your pH frequently. Only put certain plants in your goldfish tank. Goldfish, interestingly, are pretty aggressive with plants.  Some plants are better able to defend themselves: Try Vallisneria types, different Hygrophilas, Red Bacopa or even Ludwigia Arcuata. A filter is an absolutely necessary component of your fish tank. Filters operate according to flow rate, with certain filters designed for certain sized tanks, so make sure you get the right filter for a tank your size. There are two types to choose from.  External filters rest on the exterior of your tank, while internal filters are submerged within the tank.  Either type of filter can work for a goldfish tank. External filters are generally considered to be superior, as they have a greater capacity to store filtration materials and can accordingly clean water more thoroughly.  . If you have a 20 gallon (75.7 L) tank, shoot for a filter rated for 40 gallons (151.4 L). You can use tap water to fill your tank, but you need to add conditioner to make it safe for your goldfish.  At minimum, you need a conditioner that neutralizes chlorine and chloramine.  Aside from removing any harmful chemicals in tap water with conditioner, you’ll also need to make sure the water has the right pH level for gold fish, which is a slightly alkaline 7-7.5, ideally 7.2 pH.  Use a pH test kit to periodically test your water, and adjust the pH if necessary. Take tank placement seriously.  Do not place the tank near a window or any heating or cooling source.  Do not allow sunlight to hit the tank directly.  Also be sure the tank is set on something flat and extremely sturdy.  You likely don’t need a heater.  The fish tank’s water temperature should be between 60 °F (16 °C) and 72 °F (22 °C), so the ambient temperature of your living space should work.
