I have one that I got for a super deal our first year of homeschooling four years ago. I found it at Hancock Fabrics, but it’s just a Scotch brand one that you can pick up in lots of places.
I use it occassionally and am happy I have it, but I wouldn’t say it’s a must have. I use it for both school things and home things. For example, I recently made a blank dinner menu and a chore chart and by laminating them, I can use a wet erase marker on them and reuse each week. I also made a school calendar our first year that we still use and I laminated all the numbers so they would stand up to taking them off the calendar repeatedly. We have laminated game pieces for a My Father’s World geography game we had for our first year. In our 106 Day of Creation science, I laminate my boys’ “days of creation” dividers they make before they put them in their notebooks. Oh and we sometimes make bookmarks and I like to laminate tho for durability.
Now listing all that it sounds like I use it a lot. I guess I have, but it’s not something I use weekly or even monthly, but I am happy I have it. Hope this helps you!
P.S. My sister said Harbor Freight sells laminating pouches really cheap and combine that with a coupon and it’s even better. I am still using the package I have, but will buy them from there when I need more. I just peeked and they sell laminators too ~ http://www.harborfreight.com/9-inch-hot-laminator-92499.html (remember ALWAYS use a coupon – they have 20% and 25% off all the time).
