Decent looking, quality patched. Did not try to adhere them yet but I reinforce iron-ons with additional fabric glue anyway so that would not be a complete deal breaker for a crafter if in fact they didn't adhere well. I recommend. Sturdy soft patches, vibrant color.These patches look great and you can't beat the price. We ironed them onto a backpack and my NASA loving 4 year old is thrilled.The iron on adhesive that comes on the patch is terrible. I ironed them on, and the edges didn't stick. I nudged one and saw that they would easily peel right off. I tried again, using some iron on adhesive from the fabric store (HeatnBond ultrahold) and they are now securely attached.Ok guy's listen uppp! because I know what you're looking for and yes these are it. It is great,fit well for bookpacks Jean's jacket hat's everything. It's going to look really cool and amazing. But here's the you need to understand and research what kind you want to do, meaning if you want to sew it on/ or iron it on or / Lupe and Hook. There 3 different ways you can go about it. I made this mistake the first time. But it's ok because I give them to my best friend and he love them. I already ordered the one's that I need because there are really cool and great.These are cool! The colors aren't as brilliant or well matched to actual NASA gear but for the price they're pretty great! I use these patches for my space suit that I wear for kids programing so I'm not worried about how authentic they look, just that from a distance they look appropriate.I would buy again.They’re kind of thin but that’s OK I know the little space shuttle wasn’t trying to stick to shirt but I just had to leave a shirt for a good 2 to 3 minutes and then I was able to stay I enjoyMy son got a hole in his jacket, and we used one of these to patch it up. The adhesive lasted about a month before half was off. Not surprised. All patches I've used I've had to eventually stitch it on by hand.I live these! I didn’t use the blue Nasa patch, I added a different patch I had. I would definitely recommend sewing them on as well as they will fall off quickly if you only iron them on. The quality is surprisingly good for being so cheap, and they look great. Great purchase to make my backpack look less boringPatches didnt iorn on all that well i ended up stitching them on instead. But quality is good.I like how they come so professionally finished and sewn with care. They are very easy to apply to polyester and cotton materials, within a few minutes of heat and a moist cloth and its on for good. It makes clothing look so much more expensive and can be added to many pieces for an enhanced look.
