、。
Mother gave me gloves that she had made herself.
Literal
Mother [topic-は], mother self [by-で] made gloves [obj-を] gave-me (polite).
母自身 ('mother herself') is the reflexive form: [noun] + 自身 = 'X itself' / 'X herself.' The で here is the agent/means marker, and 母自身で作った is a relative clause modifying 手袋. くれる is the plain form of くれます and always implies the action is done for the speaker (or in-group) — so there's no need for an explicit '私に.'
