Pretty simple question, I think:

I'm extending 3 window jambs, 1 exterior door jamb (main front door), and one interior door jamb (into kitchen) by 3/8".

I have all the trim that will hang back up after, but what are my best options to do the 3/8" extensions? In other words, I need lumber etc. 3/8" deep and I'm trying to save myself time without needing to rip something down to fit it in the jambs to extend, width wise? I hope that makes sense. Any recommendations would be great! Thanks.

If I understand you, you need jamb extensions which happens all the time.
But you need to use solid lumber and rip it to whatever size you need.
Is it going to be painted, is it interior or ex. Give a little more info.

Yes, I agree. Sorry my question was not clear. I'm trying to avoid ripping the lumber. I'm wondering if there is any common lumber, trim, etc. that is 3/8" deep and 3/8"-1/2" wide. In other words, obviously I can find lumber that is 3/8" deep but I'm trying to avoid ripping it to the width, if even possible.
