Well, theres really nothing wrong with steaming i guess. I never had one when I started doing upholstery, learned to work without one, and now i realise that i dont need one. Steaming cloth or convertible top material could come in handy, but when you steam leather, it has a tendency to get hard. Ive heard of guys steaming parts of headliners that are made out of leather to get them to unwrinkle, i dont think i would do that. And I guess i dont do hardly any reproduction tops at all, a steamer would come in handy for those. The few that i have done have required a lot of tugging and stretching. 99% of all the tops i do i make on my own (hand sewn, hand made patterns), and I guess a top sewn from good patterns shouldnt need to be steamed to get the wrinkles out. But a production made top cannot be made vehicle specific, and even though the cars were made on a production line, they still will vary. I didnt want to sound like I was saying steamers dont work, cause Ive never really used one. I guess id rather make a few more pulls to get the wrinkles out.
