I might be able to get by following the Levitacal precepts, but it would be tough. I see myself wearing leather sandles, blue jeans - "LEVI'S" of course, and a cotton tee, or wool sweater. If you support a no mixed fabrics approach, and embrace cotton. You will be supporting American cotton farmers.
But, seriously. It's interesting that the imagery of weaving mixed fibers is used. The existence of DNA was learned in our time. Mixing two strands of differnent fibers, reminds me of two strands of DNA combining. In this case, it's warning about what not ot combine.
