Open Photoshop and use the File New command in the top menu. Enter the following information into the popup window, then click OK: Width and height: Choose A4 for a typical sheet of paper, or 3000 pixels wide x 2000 pixels high for a landscape collage or set any size you like. Resolution: Enter 300, or 200 if using a slow computer. Switch to a smaller value if the collage is very slow to edit or open, or use a larger one if the pictures look pixelated. Color Mode: RGB color Background contents: Choose Transparent if you plan to add your own background image. Otherwise, choose White or Black. Most collages look best on a wide, landscape style canvas. In the top menu, use Image Rotate Canvas 90 degrees to turn the document onto its side. If you'd like a background, choose any image file on your computer. Open the file using the File Open command in the top menu. Drag the image onto your collage, or use the following commands: Click the background image and press Ctrl+A to select it. Press Ctrl+C to copy the image. Click the collage window (called "untitled 1" unless you saved it). Press Ctrl+ Shift+N to open a new layer. Find the Layers panel and click "Layer 1." Type in a new name: "background." Press Ctrl+V to paste the image into the background layer. Adjust the background image as desired. The slider above the name in the Layers panel makes it more or less transparent. Ctrl+T lets you resize or rotate the image. If you added a background, use this step to delete extra space around the image. Navigate to Image Trim with the top menu. Check the boxes next to "transparent pixels," "top," "right," "bottom," and "left." Click OK. If you'd like a frame, insert this by double clicking on the layer name "background." In the pop-up window, make the following changes: Click on "stroke" and check the box next to it. Change the position to "inside." Alter the size and color however you like. Check "inner shadow" if you'd like a shadow inside the frame. Click OK when finished. Go to File Save and name your document "photoshop collage," or a specific, memorable name. Save frequently as you work on the document, so your work won't be lost by mistake.

Summary: Open a new document. Make it landscape style. Insert a background. Trim the background. Add a frame. Save your document.

Tap the Arrow button (iPhone) or the "Directions" (iPad) button at the top of the screen to create a new trip. You can enter addresses into the Start and End fields, or let the Start be your current location. If you've placed a pin, the default End point will be that pin. You can change your mode of transportation by selecting one of the icons at the top. Selecting the Transit icon will prompt you to install a third-party transit app from the App Store. You can swap your Start point and End point by tapping the curved arrow next to the text fields. Tap "Route" to see the route from the Start point to the End point. You can set a destination from any pin on the map, either search results or a pin you've placed. Tap the pin to make a bubble appear above it. This bubble will say the name or address and have a car icon with a time underneath. Tap the car icon to set the location as your destination. When you set a destination, the map will change and show the route from your current location to your destination. The route will be highlighted in dark blue, while alternate routes will be highlighted by faint blue. The estimated times of each route will be displayed along the route itself, as well as at the top of the Maps screen. If alternate routes use a different means of transportation, such as walking, you will see the icon next to the route's time. Tap the List button at the bottom of the screen to see the entire list of turns from start to finish. You can scroll the list if there are too many turns to fit. Click the "i" button at the bottom-left corner of the screen, and then tap "Show Traffic". Heavy traffic will be indicated by red dashed lines, while moderate traffic will be represented by a smaller dotted line. If there's a lot of traffic on your route, consider trying one of the provided alternatives. When you tap "Start", the navigation mode will begin. The map will change to orient to your current direction, and the current instruction will be displayed at the top of the screen. Maps will scroll through the instructions as you proceed down the route, or you can slide through them with your finger to see how each turn looks. If you stray off your route, Maps will automatically try to calculate a new route to reach your destination. If your iOS device is connected to an AirPrint printer, you can print your map by clicking the Share button and then selecting Print. Select your printer and choose the number of copies. A map of your route along with turn-by-turn directions will be printed.

Summary: Create a trip. Set your destination from a pin. Review the route. Review the turn-by-turn directions. Check the traffic. Use the navigation mode. Print your directions.

Generally, you need chemicals to remove polyurethane. Because these chemicals are often harsh, you need good ventilation to protect yourself. If you can, go outside to work. If you're working on floors, create cross-ventilation to help keep you safer. To create cross-ventilation, open the doors and windows in the room. Also, it's a good idea to set up one fan blowing inward and one fan blowing towards the outside to get the air moving. If you're working on a piece of furniture inside, you should put something down to shield the floor from drips. A plastic tarp underneath the piece of furniture should work well to provide protection. You can tape down the edges if you're worried about tripping. Paint stripper can do a number on you if you're not careful. You'll need rubber gloves to protect your hands. Wear goggles to protect your eyes. Finally, you'll need a vapor ventilator mask, also known as a respirator, available at hardware stores, so you don't inhale the fumes. You should also wear closed-toed shoes, long sleeves, and pants if possible. Chemical-based paint strippers, such as those with methylene chloride, are very effective. However, they're also more harsh on your skin and can cause respiratory problems if you're not careful. If you're worried about the effects, you can use water-based strippers instead, though they do take much longer to work.

Summary: Create cross-ventilation. Protect the floor. Protect yourself. Choose your paint stripper.
