Resurrecting this thread for a quick question. A client wants to run a gold shimmer on an order, half on 100% cotton tees and half of the order of NL 60/40 tanks (navy). While I'd love to talk them into 100% cotton tanks as well, before I go that route I wanted to see if I should expect an issue not underbasing on the 60/40 tanks? I have a small oven and struggle keeping my temp low for an appropriate dwell time so my gut tells me I should use a black blocker ub. My preferred route would be to use a wb black blocker with warp drive and Wilflex Gold Shimmer on top, but as a less appealing alternative, I could run Wilflex Performance in the ub as well. Regardless, I'd love to run the 100% cotton and blends the same for a similar look. Thoughts on this?
