I am new to the forum and appreciate any help. I have been in the sign business for over 2 years now and have purchased the Digi knight Combo heat press. I ordered some thermoflex which is great but does anyone know how well this holds up in the long run? Also I found a material at a much lesser price called spectra cut. Does anyone know the difference and am I looking at an inferior material here compared toi thermoflex. I built my sign business on quality and I want to do the same with my new shirt venture.
