For everyone that has multiple colours on the plane. Do you just iron on the covering over the other colours, or do you have to cut the pattern out then only overlap a little for the multiple colours ?

I guess what I'm asking is: Can you iron covering on top of covering ? Will it stay in place ? Can you do it with both monokote and ultracote ? (ie monokote on monokote and ultracote on ultracote)

Thanks
