A combined pedigree is easy if you put one of your children in the first generation (proband) position of any pre-printed pedigree chart (since you aren't using software). Or you could leave that box blank, even as you fill out the rest with you in the father box and your wife as mother. Most pre-printed charts have a limited number of generations, but can be linked to another sheet which extends the tree. (Each name in the rightmost column can become the first name on the next sheet).
 combined tree can be created by importing the relevant names together. However a particular person would have to be in the tree to put in the 1st position on the chart.
