Large Appliqué Help

I am drafting a project right now for a gift. Basic info, I want to create a blanket with an appliqué of their car in the middle. I think this might be easier than crocheting the car into the pattern of the blanket, especially since I plan on using Pattern Princess' Cottage Garden Throw for the blanket (https://patternprincess.com/cottage-garden-throw-blanket-crochet-pattern/), using two similar colors so it's more of a neutral background.

But I've never done an appliqué of this magnitude before, and I'm not sure how to go about it. If anyone has any tips, sites, or guidance, I would be grateful for the assistance!
