Easiest route these days is to toss in a couple major/legendary brittle artifacts. Usually Animated of haste/mystic of sorcery name combination. Otherwise if you are trying to legit craft the resists you will need to do something along these lines.
Assuming Studded Armor. I would just do regular studded for leather consumption and ease of exceptional craft. Also Studded gorget gets an extra resist over studded mempo.
For Cookie Cutter Approach you can use the schematic below. A little bit difficult might take you some time.
You need 1 of each of these. All enhanced with Barbed leather in the end. Each of these has 2 points of wiggle Room. You can Also do left to right crafting. So once you get your First piece, if the resists are in a slot other than what you are imbuing. You can subtract it from the next piece, so on and so forth until the end.

As a Straight forward crafter its usually best to just craft a bunch of pieces and save all the ones with 1-2 minimum Resist slots. for Leather its 2/4/3/3/3, Studded 2/4/3/3/4 other than a mempo. These will get you the Most Resists on the end piece after imbue.
