It's interesting that it's specifically recorded that the offering was made to the Lord, not to the tabernacle. In fact, this story is amazingly God-centered. God is present in every step of the process:
-God details the need
-God tells how to use the supplies
-God prompts Moses to ask for them
-God prompts certain people to respond
-the people give to God
-the gifts are used to glorify God by craftsmen God gifted.
