Muslin is intended to be mockup fabric, and it's cheap, so it's a good starter fabric. It also takes well to being written on in pencil and marker, which is a handy characteristic if you want to do markings directly on the fabric as you're starting out. If you can get weird clearance fabrics (like polyester blends - satin is a big one), you can practice working with non-cotton fabrics, since they behave differently (slippery, fray, etc)>>9943206>good taste OP
Look up "EL wire" -- you can get a lot of it for cheap on eBay or other non-specialty sites, and you'll need to hand-tack the wire down along the seam (and think of a place to hide the battery pack - probably an interior pouch sewn along a back panel)>>9942462
Can't help you on the specifics of a cooling garment, but>resources and equipment
- Sewing machine is helpful, especially for garments that you intend to wear in medium/high-stress situations (or: learn to sew by hand. It takes more time, but it's more precise and you have more control over certain areas)
- Fabric scissors: different from regular "paper" scissors - they're sharper and will cut fabric more precisely
- A way to mark the fabric: soluble ink pens, chalk, etc
- Sewing pins
- A big space to lay out fabric for cutting (kitchen tables work, clean floors also work)>test and buy fabric and thread
Find a fabric/crafts store near you. If you're in the US, JoAnn is a national chain retailer of sewing shit, and they do classes on sewing, too.
For buying specialty fabric, you can usually order swatches online for sampling at home - getting the feel of it, seeing if it works for the project you have in mind, etc. By testing swatches first, you don't end up committing to a $60 purchase of expensive-ass fabric that is completely wrong for what you need.>>9943604
imo it's more impressive if a cosplay is built well enough to withstand multiple wears, rather than something flashy with shit construction that's falling apart after six hours.
