Perfect Repair
Color: Cherry, Size: 2.4"x 15ft
We purchased a used secretary with hutch, and it had some damage on the veneered decoration on the hutch doors. I discovered this product and ordered the closest match I could find. It was easy to cut to fit and the price was amazing. It looks so good that you could not easily find the repair and I am very happy.

Professional look overall
Color: Birch, Size: 1/2"x 25ft
Installing the edging worked best with a heat gun vs a blow dryer, Adhesive was average, some areas adhered well while some spots kept lifting. The areas where the edging is connected to create the continuous link are very visible and will not blend well when painted. I had more waste by trying to avoid these sections. The edging is easy to cut. I used 220 sand paper to blend the areas where the edging was too wide for the project edge after trimming. Be careful not to over sand the edging. I found both the 1/2 in and 3/4 in are both wider than 1/2 in and 3/4 in plywood. Expect extra time to trim the excess. The edging is flexible and easy to use when working with curved edges. Overall, the edging still gave my projects a professional look.

A Good Solution for Rough Edges of Wood.
Color: Birch, Size: 1"x 25ft, Color: Birch, Size: 1"x 25ft
This is a great product. We needed to recover the booth in our motorhome because the faux leather is peeling. The booth is made of plywood and has rough edges. We opted to cover the booth with heavy wallpaper, but needed something to cover the rough edges. This product is really affordable and very easy to use. It adheres pretty well. We had planned on painting the wood veneer edging, but we decided that the wood tone fit right in with the rest of the trim in the motorhome so we left it raw. While I bought 1" because that is mostly what we needed, some other areas were only 3/4" wide. It was so easy to run an Exacto knife along the extra edge and trim it smoothly.
