Some rewards are easy to combine. For instance:
If you'd like a custom sketch card but it isn't already part of that pledge level (or if you want more than one), simply add $5 for each card.
If you'd like a button pack but it isn't already part of that pledge level (or if you want more than one), simply add $10 for each button pack.
If you're pledging on a level that only offers SEASONS OF GROWTH but you'd also like SOWING SEEDS, or vice versa, simply add $20.
Some rewards are more...interesting to combine. Here is how to combine the "limited rewards":
If you are pledging for one of Rafer's pieces of original artwork (at either the $100 or $150 level) and you want a custom sketch from Rafer or Mal or Dale or Jake (which is also a limited reward). Well, I can probably talk people into drawing 1 or 2 more pieces beyond the limited pledge level. So, you should choose the piece of original art as your pledge reward (since there may only be one of those) then MESSAGE ME to make sure I haven't already overbooked my artists, then add $40 to your pledge for the additional drawing.
The same goes if you want a drawing from both Rafer and Dale (or Mal and Jake). Message me to make sure it's cool, then add $40 to your pledge.
If you want two (or more) pieces of original art...there are far too many variables. Message me, and we'll work something out.
Did I forget something? Message me and we'll figure this thing out together.
