While Kurt Adler is my favorite wooden Advent calendar maker, there are several other companies that produce wooden Advent calendars that are wonderful gifts for any children that you have in your family.
Some of the calendars come with magnetic attachments to keep the calendar together, and help from losing any of the parts. You can also buy Advent calendar kits to finish your own Advent calendar, adding personal touches such as names of family members or details that relate to your family personally. If you have artistic ability, these make a unique gift that no one else will have, a one of a kind treat for your family.
If you are not artistic, don't worry, because you can appreciate the artistry of other Advent calendar makers including Kurt Adler, Fontanini, Byers Choice, and eeBoo.
