[header] How to write a home improvement contract [title] Define what you want to do. [step] You can't write a good contract unless you can define exactly what you want to accomplish. Whether it's a major project like an internal remodel that includes adding rooms or rearranging walls, a new bathroom, or merely adding lighting, you must have a firm grasp on all aspects of the project. <sep> (A) [substeps] A full contract makes certain kinds of health and safety issues more likely. If you try to get your home as good as possible, the other person might skip ahead to any settlement offer. (B) Your objective should be clear from the outset, however. [substeps] Don't wait around for the right time. (C) [substeps] Make sketches or print out photos that closely match what you would like to do. This can help you when selecting a contractor and writing the contract. (D) [substeps] If you need to include a unique color scheme, don't just list and label certain, however. You don't need to thoroughly describe every detail of the project, either.

[header] How to use metallics in your wedding decorations [title] Decide how bold a statement you want to make with metallics. [step] In most cases, metallics work best as small accents in your wedding decor. However, you can use larger splashes of metallics to make a bolder statement. <sep> (A) Choose a bolder statement color for your decorations. [substeps] Red, orange, purple, black, and plum are the most common metallic colors used in any wedding decor. (B) [substeps] For example, you might want to create a statement like a star, necklace, and flower in your wedding color scheme. You may want to try a solid color such as brown or ivory. (C) Keep in mind that your decor will have a more dramatic look, though, so a heavy dose of metallics is more suited for a formal or evening wedding. [substeps] If you want to go heavy with metallics in your decorations, it's best to pair them with a neutral color palette. (D) Go for more of a statement by drawing out bold combinations of colors that a person could use with metallics. [substeps] Bright, bold, and flashy colors like neon and bubblegum yellow are great accents.

[header] How to prevent hair color from bleeding [title] Use conditioner to keep color dyes from bleeding onto lighter hair. [step] During the dyeing process, coat lighter hair in conditioner to protect it. The conditioner will act as a shield when you rinse the dye itself out, lessening the unwanted contact that the dye has with your hair. <sep> (A) [substeps] Make sure the conditioner is water-proof for water dyes, as water can increase dye absorption into your hair. Do not use " water-proof " conditioner as this can affect color oxidation, and water can halt dye absorption. (B) [title] Wait 24 hours before shampooing your hair after getting it dyed. [step] Washing it too early can dislodge the coloring agents. (C) [title] Apply a heat protectant product to ensure your hair does not get too dry. [step] The most effective, but sometimes needed, heat protectant formulations are laser hair straighteners, which shrink hair with a low heat setting. (D) [title] Always apply conditioner to your dyed hair immediately. [step] Doing so will promote the color to fade, lessening the time it needs to remain in your hair.
