Gallery Glass Instant Lead Lines, 72 ft 1/8" Thick, 16690 , Black

Easy to use, gets the look I wanted. Too expensive for what it is, but I do like the results. This is not a toy!!

I am really glad I didn't let the negative reviews deter me from using this product. I'm still in the process of finishing the massive undertaking of applying faux stained glass treatments to my all-glass double front doors and two giant windows, but I really had to just come and drop a much better review for this product because it's really nowhere near as bad as the reviews are making it seem. I do have some tips to make it work better, though:First of all, you will need to make sure your window is clean. SQUEAKY clean. Use window cleaner, then use Everclear and a squeegee. Having absolutely no lint on your window at all when you apply anything like this to it will give you the best adhesionSecond, do NOT let your fingers touch the adhesive!!!!!!!!!!!! I can't put enough exclamation points behind that statement. Anywhere my fingers touched the back of the leading, I had trouble with sticking. Since that is usually the edges which is where you need adhesion the most, expect to cut a little bit off of each lead line if you want to maintain the best possible adhesive.Third, and this was what I think really clinched it: I bought clear gallery glass and ran a thin strip of it wherever I wanted my lead lines to go just before adding the lines. This thin line skipped in a lot of spaces and dashed, but that was perfect for what I needed. I would wait a few minutes until the gallery glass was tacky and then press my line into place. The clear gallery glass filler liquid acted as a glue, bonding the lead lines and glass even better than expected.Finally, once you've stuck this down, don't move it. At all. If you have to start over, use a new lead line. The adhesion will never be the same. Map out your line and apply it slowly and methodically to be sure you won't need to go in reverse. Trust me, this can be done. My lines are all straight lines and right angles, so if I can make it happen, you totally can do it! To finish your look even more, make sure to purchase the same color in the liquid leading to create "joints" where true leading would meet and be soldered.Overall I just want to let anyone who is considering using this product know that if you pretreat your surface properly and handle/apply these lead lines with care, this product works fantastically and will absolutely enhance the finished look of your project tenfold. I was so close to going without lead lines (looked ridiculous and bare) or just trying to use the squeeze bottle (oh god, that was JUST AWFUL), so I'm really really really glad I didn't do that and took the risk on this purchase. I most definitely recommend these and think they work great for what they're meant to do if used the way they should be used.

Really cool product for faking it till you make it. It basically nonmagnatized magnet material. Cuts are straight. Sticky is great. Super easy to use. Wish list : grayer in color and rounded instead of flat would really sell the illusion.Definitely hit the joints with the liquid lead.

nice for stain glass crafting

Perfecting the Plaid Gallery Glass liquid leading technique is not impossible, but for anyone who doesn't have a surplus of free time, it's incredibly challenging. This is where their Redi-Lead comes in and saves the day. Especially the Value Pack, which answers the needs of those of us who are working on larger pieces. This is the most cost effective pack of Redi-Lead too, so I'm somewhat surprised that it's not always available in craft stores.If you're feeling unsure about trying this stuff, don't be. It's super easy to use and if you don't get it laid out exactly as you want it the first time, no problem. Just peel it up and replace it where you want it. Don't worry about it losing it's stick factor either if you have to reposition the line you're working on. On my current project, there was one piece I had to redo 4 times before getting it exactly how I wanted it, and that stuff was sticking securely each time. Another plus: it's flexible enough to form perfect circles, but dense enough to lay a straight line without any trouble.IMPORTANT: For a more authentic, more finished appearance to your faux stained glass project, I strongly suggest that you purchase their liquid lead product to dab the Redi-Lead seams with. it really does make a difference.

Bought these and the paint for my front door to create some privacy. The lead lines are really the most difficult and time consuming part of the process. They dont bend very easily and they lose thier adhesion if you reposition them more than a couple of times. They are also pretty difficult to cut unless you have a really sharp craft knife. On the other hand, these stickers worked so much better than the lead line black paint that comes in the stained glass paint kit. I reccomend them, just make sure you give yourself several hours or days to complete your project. Hope this helps!

Been using these lead lines for large window projects for over 10 years. Do not use a knock-off - use THESE. They are a superior product from Gallery Glass.

I have just recently started using these lead lines so I don't have experience as some have had with the older version that is supposedly better. These work pretty well for my purposes. I use them as fake lead lines on my faux stained glass projects and they really look good. You do have to be careful not to stretch them (they will shrink back and be too small!) and don't over handle them or they won't stick well and the glass needs to be very clean. Occasionally, they don't seal real well and paint will leak under a little but I usually just let it dry then scrape it off. I have used them on curves but they don't work well on tight curves. Instead, I cut the strip into smaller bits to make the curve and then used the liquid lead to cover the joints. I do wish they stuck and sealed a little bit better but I'm managing with them as they are. Have bought twice so far.
