Question
What is/are best way(s) to save veggie seeds from garden overwinter?

Answer
Dear Louis,

The National Gardening Association Magazine has an excellent article about the seed saving process on their website.  The article is oriented toward young kids to stimulate their interest in gardening and conservation.  The article is well written and best of all it answers your question in spades!! Therefore, I'm proving you with an Internet website link to it below:

Should you have additional questions after reading the article, then please post another question.
