We literally have hundreds of ornaments
We get one for each family member a yr to remember that yr by and then if we go someplace on vacation or whatnot we get others. We only get oranments that mean something, we got rid of the "knick knack" non sentimental ones yrs ago.
I have the ornaments sorted by family member or "theme" as we have now branched out to several trees in our home. For instance I have a tree that has all our college team ornaments on in the family room. For instance DH has a tub full of ornaments that are "his", his baby ornaments the ones he made in school or all the "dad" ones he has.
They are each placed in a bubble wrap envelope unless they have a box (I usually only keep the Hallmark boxes and any collectible or fabric type boxes) the Bins are labeled.
I got the bags at a big box store Duck brand makes a 100 bag assort. that I got at walmart but they look similar to these:http://www.staples.com/office/suppli...Feed-_-listing
We are a point that we have several large tubs. The ones that are not too many are sorted in smaller tubs placed in a larger tub that we keep the tree skirt,stockings and angel in.
