Contradiction with Exodus 26:1
Exodus 26:1 describes the detailed construction of the tabernacle, which complements rather than contradicts Exodus 26:10.
Exodus 26:1: Moreover thou shalt make the tabernacle [with] ten curtains [of] fine twined linen, and blue, and purple, and scarlet: [with] cherubims of cunning work shalt thou make them. [of cunning...: Heb. the work of a cunning workman, or, embroiderer]
Contradiction with Exodus 26:12
While Exodus 26:12 describes additional requirements for the tabernacle, it aligns with the construction details rather than contradicting Exodus 26:10.
Exodus 26:12: And the remnant that remaineth of the curtains of the tent, the half curtain that remaineth, shall hang over the backside of the tabernacle.
Contradiction with Exodus 35:11
Exodus 35:11 reiterates instructions for the tabernacle construction which are consistent with Exodus 26:10 rather than contradictory.
Exodus 35:11: The tabernacle, his tent, and his covering, his taches, and his boards, his bars, his pillars, and his sockets,
Contradiction with Exodus 36:9

Exodus 36:9: The length of one curtain [was] twenty and eight cubits, and the breadth of one curtain four cubits: the curtains [were] all of one size.
