I found ceramic biscotti jars (already filled with Nanna's choc biscotti) at Staples for 9.99. Save the prepacked cookies for a another occasion and fill the decanter with your treats!
Three different ceramic Italian themes were offered. Each pattern glazed onto the containers. Very nice and a surprising find at Staples office supply.
I did this with an old mayo jar and new mason jar lids, but if you go to a Smart n' Final or other restaurant supply type store, they'll have quart sized glass jars. Now that I know these jars are so useful, I'm having all my friends collect them throughout the year so I can clean them off and just buy the lids next year.
