How do you make Christmas garland?

You can take stout wire (hanger, etc.) to support the garland. Then add fake or real pine boughs, and fasten on ornaments or other things to fit your theme.

JULIE....Creating Custom Christmas Garland is a utube you can watch. She really has some good ideas.

Purchase and place your garland where you want it. Attach wrapped candies and candy canes using fishing line. Tie them onto the garland and put a pair of scissors on a ribbon close by on a wall using a command strip. Let guests cut a piece off when they leave or arrive.

If you are still looking for edible garland ideas, diy from mini marshmallows and fruit loops can be a fun activity. 'Sew' them together with waxed dental floss.

These felt candy ornaments are bright and showy looking, but not hard to make.
