Clothes cover the skinnyness (is that a word?) up. Or in other words, no, you do not need to twist 2 pipe cleaners together. You can if you want to
And I have used floss other than DMC and I donīt really see much difference. For fanning out, I find it is best if you donīt use too long pieces. Just about my arm length (fingers to elbows) seems to be my pick. Then it is easy to fan.
Every now and then I get some miscellaneous half used packs from thrift store and I have used brands that are no longer made and off brands. Some of the stuff is less shiny, which is one thing I like about my random floss. For some stuff I consider DMC too shiny, lol. But all my floss has to coordinate really well too, I am very picky about that. I can agonize for 10-15 minutes about what color to use to best match the felt (I have a giant tangle of floss-mess)
