Making a playlist will depend on what software you're using to play music, whether online, on a mobile device, or on your computer. Making a playlist usually involves a simple drag-and-drop style of moving songs into the list, or you can select individual song files, right-click, and send them to the list. Start by making a blank list, then filling it with music you might like to include in a playlist to learn how it works. Programs like Spotify and iTunes make creating playlists an easy and almost essential part of the music-listening experience. Playlist.com, Take 40, and Windows Media Player are also all good programs for managing your music. Pandora and other Internet radio stations let you create channels, but not specific playlists of songs, unless you have Pandora Premium. Get music by typing the name of any song, band or artist you like. You can also search just general types of music or artists to find new music or check out what your friends or other users on the site are listening to. If you're using iTunes, you can either select music that's already in your library, which you own, or you can search the store and download any song you find for a price. If you've got iTunes, but no music, you can also upload your CDs into iTunes to "rip" the music directly. Going to the public library and loading the music into your iTunes library can be a great way of acquiring songs to make playlists on the cheap. . Mobile devices also allow you to create playlists instantaneously, by selecting songs and sending them to a playlist, or selecting "Play next," making you an instant DJ. You don't need to make playlists ahead of time, you just need to go with the flow.

If you're unable to find the exact clothing items you need for your costume, your best course of action is to teach yourself a little bit about sewing. Look up tutorials for basic sewing techniques and follow along. Once you've sharpened your skills, you'll be able to turn ordinary fabrics into one-of-a-kind garments. Having some sewing skills in your repertoire is also useful for adding embellishments to items to make them more faithful to your source material. Record all of your major measurements (shoulders, chest, waist, hips, thighs, and inseam) so you'll be able to tailor your custom clothing to your frame. Both of these materials are incredibly useful for crafting armor, shields, weapons, and anything else that's made up of flat surfaces and angles. Not only are they cheap and easy to come by, they can also be cut, shaped, painted, and glued or taped without any special know-how. Rummage through your closets or garage to search for scrap cardboard or plywood that you might be able to convert to costume components. If you don't have any luck, ask around at area businessesmany stores give away old boxes for free. Plywood will hold up better than cardboard if you're going to be moving around in your costume or packing it up to transport it. You can make almost anything out of EVA foam. Just sketch your design onto a sheet of the proper thickness and density and carefully cut out the pieces using a utility knife. Hot-glue the individual pieces together, carve out fine details with your utility knife, then paint your props to add color and texture. You can buy sheets of EVA foam at any craft store for just a few dollars. Browse user-submitted templates for various weapons and accessories on cosplay websites and message boards, or simply have fun figuring out how to put things together yourself. If you find a piece that's the perfect fit but the wrong color, dying it is a quick and easy fix. Similarly, fabric paints make it possible to add detailed design elements to plain garments. Between sewing and recoloring, you should never find yourself stumped about how to pull off tricky costume components again. Natural fabrics like cotton and linen tend to accept and hold color better than synthetic ones. With only some fabric paint and a few DIY stencils, you could transform a cheap shirt and pair of pants into a screen-accurate "Star Trek" uniform. Sometimes, there will be too much going on with a particular accessory to successfully recreate it using household items or materials like EVA foam. In these cases, it can be helpful to make use of a 3D printer or 3D printing business in your area. The printer will take care of the hard part for you, which means all you have to worry about is applying the finishing touches. Many companies will 3D print custom items for a price. The cost of these services may vary depending on the size, complexity, and material of your item. If you plan on making cosplay a long-term hobby, it will be worth your time to gain some experience with 3D design software like Meshmixer, FreeCAD, or Vectary that you can use to create your own models for printing.
