Ok, I'm very new to this but have found soo much helpful information here. Anyway, just a couple of quick qestions....I'm looking at different companies to buy my blanks from. I keep seeing 5.5 oz and 6 oz etc, etc T-shirts. Can someone please help explain the difference in quality of these shirts and is 100 % preshrunk any better (or worse) than 50/50? What are ya'lls preferences and/or have worked well for you? Also, researching the different types of software and am leaning towards Corel. My husband has a buddy that does metal fabrication and such that uses Flexi 8.5. Anyone ever heard of this or use it? How well would it work for us, if at all? Thanks in advance!
