I am new to the hobby and have bought a few panes from the USPS of that have multiple stamp designs. I would like to remove a strip or block of the multiple designs from a pane for my collection but I noticed that some panes do not have die cuts where I can separate the stamps I want. For example, I bought the "Innovation" pane of stamps (Scott 5518a) and each of the stamps perforations seems to be nested in the next stamp so I can not simply cut the stamps I want out without cutting the perforations of both stamps like I could if it was imperforate.
I wanted to know if someone could please share their knowledge on the best way to separate the stamps I want for a strip or block since I do want to include these in my new collection. Do you use scissors, exacto knife, etc., and what technique do you use to cut the pane?
