Spandex sewing guides

Hello, I wanted to start a thread here for people to share any tips, tricks, tutorials, or guides to sewing spandex. Whether that is basics to sewing techniques, making modifications to gear, repairs, or up cycling. Personally I’m a pretty decent seamstress, but find sewing spandex difficult and am always looking for online guides. It’s hard to find guides for more fetish style gear like bulge wear. So if anyone in our spandex community is a maker or has experience sewing spandex, please share your knowledge. Share links, YouTube tutorials, or in person classes if your area offers them. Gear can be expensive so let’s empower each other to make what have last as long as possible and have the confidence make old into new.

I have only attempted Poser ruched back style bikinis.  I did find the Robert Joseph Sewing and Sew Skimpy channels on Youtube that have some male patterns. As for technique probably the womens swimwear tutorials and cosplay ones are going to be as helpful in managing the fabric.  I pretty much take an existing old garment de-stitched it and altered it to fit my needs.  I also found that a serger,  and an elastic foot for the sewing machine helped quite a bit.  I also look for spandex that stretches 4 ways so there is less concern when laying out the patterns. 

Not specific to spandex or the like, but more for sewing in general. Nancy Ziemen and her public television series, "Sewing With Nancy" is also a good resource on sewing techniques and tips.
