I have a Clover II mini iron for pressing the seams. It doesn't have a steam function & I find I don't need it. I generally use a LOT of starch, but for seams I mostly just press & go. If it's being especially stubborn, I might mist it with a bit of water to reactivate the starch that's already in my fabric from the first times I pressed it (press before cutting & pressed after cutting, both with heavy starch). But usually that isn't necessary.
