Learning this industry (t-shirt design/customizing) gave me different thoughts on how to begin, continue and grow. Everyone has different opinions and suggestions. I found you have to know what products (vinyl, t-shirts, etc.) work best for you and what machines (cutters, heat press, hat press, mug press, etc.) you like and can afford. That means you need to try different product lines and test your products before you sell. You need to know how they are going to perform from when the garments get washed or just simply from over time of wearing them. Examples may included wrinkling of vinyl, lifting of vinyl, shirts fading or not, shirts shrink or not. When it comes to your machines you need to make sure your heat press has equal heating all around the platen, if not your design may not hold well in one area. Also make sure you have enough pressure when pressing your designs or they will not hold to the shirt correctly.
If you decide to follow someone online to get there input or their experience make sure you are following someone with good reviews and years of experience. Don't jump from person to person you will never find your own way in this business. Again, everyone does things different.
If you have any questions please respond and I will try to answer the best of my ability.
