You may set up a shoe rack by the front and back doors to make it easier for people to remove their shoes. To protect your carpet and keep it clean, place mats and rugs down in high traffic areas. Have a welcome mat by the door and put rugs in the living room or bedroom. This way, you can clean the mats and rugs by running them through the washer or by vacuuming them. This will save you from having to do major cleans on your carpet. To really keep your carpet fresh, nothing beats a deep clean. Try to do this at least once a year. Do the deep clean yourself or hire a professional carpet cleaner to come in and do this for you. To do a deep clean of the carpet yourself, you may want to invest in a steam cleaner. If you use a steam cleaner on your carpets, you can use a vinegar and water solution to clean the carpets. As the carpet dries, the vinegar smell will fade, leaving you with clean, fresh carpet.

INPUT ARTICLE: Article: As soon as you are done using your mop, rinse the head under hot water until the water runs clear. Then, wring your mop head out as completely as possible and allow it to dry in a well ventilated area. Let the mop dry completely before you store it again. If possible, let your mop dry in the sun. You can even let it dry outdoors if it’s a hot day to help expedite the process. Your mop will need a deep clean every three to four uses, or whenever it starts to smell funny. Sanitize your mop head by adding a cup or about 237 milliliters (8  fl oz) of white vinegar or three percent hydrogen peroxide, or half a cup (118.5 ml) of bleach to a gallon (3.79 l) of hot water. Allow your mop head to soak in the solution for ten minutes before wringing it out and letting it dry.  Do not use bleach on sponge mops or synthetic mops. It will cause the materials to degrade. Instead, try the vinegar or peroxide solutions. Make sure you let your mop dry in an area with good ventilation, and store it safely away from children and pets. Some mop heads, such as those made with towel or cloth strips, can go straight in the laundry. Detach the mop head from the handle and wash it on a hot water setting. Then, allow it to air dry before reattaching it to the handle.  Add a cap of bleach to the wash to help disinfect your mop head. Wash your mop head with items that you don’t mind getting beat up, such as other cleaning rags and towels. Mops with removable heads can also be washed in the dishwasher. Simply remove the mop head and place it in the top rack of an empty dishwasher. Add a cup (237 ml) of white vinegar to the detergent dispenser. Then, run the dishwasher on a normal cycle. Once the cycle is over, squeeze out the remaining water and allow the mop head to air dry before using it.

SUMMARY: Rinse the mop head after every use. Soak your mop in a cleaning solution after four uses. Wash detachable mop heads in a washing machine instead of soaking it. Rinse it in the dishwasher instead of a washing machine.

In one sentence, describe what the following article is about: Attach it to the cutting mat.  Trim the ends and cut it to a width of 1 1/4 inch (3.2cm). Cut to the edge of the wallet. Place about 1/2 inch (1.3cm) inside there. Tape it around the bottom edge, making sure the ends of the other tape is smooth. Bring it back to the inside and let it tape to the inside of the bill fold about 2 inches (5.1cm).  Keep it close to the edge.   Do not go to the edge of the wallet.
Summary: Take a piece of the pocket color that is 5 inches long and tape it to the left side so that 1.5 inches (3.8cm) are on the outside, and the rest folds over to hold the pocket on the inside. With the X-ACTO knife,cut off the ends very close to the wallet. Repeat on the right side. Take a 10-inch (25.4cm) piece of the pocket color. Use the X-ACTO knife to score and cut the tape holding the bill fold closed. Put one end on the inside of the bill fold, behind the pockets. Keeping it straight along the edge, tape the piece down to the bottom of the wallet. Continue along the outside, straight. Repeat on the other side. With an X-ACTO knife, score the two pockets that were just covered. Pull the pockets open and saw the pocket to right near the edge of the pocket. Repeat for all four pockets and the bill fold.

If the puzzle is already in cube form or if you’ve been working on solving it, you’ll need to start over. Unwind the pieces so it makes 1 line that looks like a series of stairs. Arrange the line so the pieces at the end of the left-hand side point up and the pieces at the end of the right-hand side point down. The column on the farthest right will be pointing downward. Look for the third diagonal column to the left of the right-hand edge, which should be pointing up and to the left and have 3 cubes. Fold the 3 cubes of that row 180° toward you underneath the puzzle so they are now parallel with and even to the row next to them. Take the 2-cube column next to the 2 parallel columns and rotate it back 90°. Then rotate the column on the end 90° upward so the 3 cubes are vertical. Keeping your hand on the last pieces you moved, rotate both columns inward toward you 90°. Then, push the 3-cube column down and away from you 90° so it is parallel with the floor. Find the bottom cube of the second 3-cube column from the left. Fold it in toward you 90°. Then, find the lowest cube on the column to the left of the column you just manipulated and rotate it 180° clockwise. Find the top cube in the 2-cube column you just rotated. Rotate it 90° to the right so the 3-column row is stacked on the row beneath it. The long piece on the right will look like stairs. Fold the last cube on the right-hand side in the 3-cube column you just rotated upwards 180° away from you so it lies flat on the row beneath it. Then, let go of the puzzle with your left hand, using your right hand to hold the pieces in the “stair” line that haven’t yet been folded. This will rotate the puzzle so the extra cubes are on top. Grasp the 2 columns of cubes that are sticking up in the line next to the partially completed cube and fold them down 90° toward you. Then rotate the column on the right side of the cube back away from you 180°. Flip the column to the right of the cube back toward you 180°. Then fold the column that is the second to the end on the right-hand side down 90°. To finish the puzzle, rotate the last remaining column 180°.

Unwind the pieces to make 1 line. Fold the third diagonal column from the right 180° beneath itself. Rotate the pieces on the right side back 90° then up 90°. Flip the same pieces inward 90° then fold the last column down 90°. Rotate the left-hand columns inward 90° then clockwise 180°. Rotate the right-hand columns 90° to the right then 180° away from you. Fold the last cube in the 3-cube column to the left 90°. Rotate the end columns down 90° then back 180°. Fold the last 3 columns into a “u” shape to complete the puzzle.
