I just finished cpoying and preparing the church newsletter and I think this is one of the best ideas I've had in awhile. The postal Service changed up the rules for mailing things, so we had to find a way to seal up both sides of the newsletters that we wanted to mail. We tried scotch tape first,but you can't open the newsletter very easily with tape. Then I noticed the letters I get in the mail from other places used stickers-like dots. Well stickers can be anything! So we had a whole box of these old labels around from back in the day.....I don't even know who has a printer like this anymore these days!
So now I just slap one of the new label seals on each edge of the newsletter and TA-DA, the postal folks love us again! AND the labels get used instead of being thrown away or being in the way! I've been doing this for about a year now and I think I'll have enough labels to last till about 2025.
