Not that it's unusual for Donnie to insist on doing things himself. He's definitely a hands-on learner, paying rapt attention as Shu exhibits how to tie things off. It looks simple enough at least.

He watches as Raph makes his attempt, half-expecting his not!brother to get his hand tied to the thing in the process. Accepting the twine and trying not to make a face, Donnie does his best to emulate how and where Shu had tied off the thing. "Like wrapping a package," he nods. "Albeit an oddly-shaped one."
