Bought this size (1/4 in) because I wasn't sure what size to get lol I'm new to making bias tapes so wasn't sure what size to get so bought 2 (in different sizes). I was thinking, oh for a few dollars I can't go wrong.I tried using this, it works pretty well. It works good if you want to make such a narrow bias tape. I can't figure out what I would use such a narrow bias tape for... so it will be left in my drawer for a bit.The quality of this tape maker is actually pretty well. It's tip is made of steel (as you can see) and the middle has a piece of plastic. Attached to the plastic is a small latch to help you pull it as you iron your fabric. The plastic piece is a smart idea because if you touch the metal with the iron, you're going to burn your fingers. Metal conducts heat after all. The first few times I've played with it, I actually was just holding it from the side to move it as I was ironing. And then I thought, oh I can just use the iron to push it instead! Yeah..bad idea. I almost burned my fingers lol Note: Don't touch the metal with the iron and then touch the tape maker lolAlso, it has a small slit opening on the bottom for you to help feed the fabric through. The space isn't that small, you can use almost anything to help push the fabric out. I used a scissor and it worked. The first inch of the fabric that comes out the feed actually don't look 'perfect' because it wasn't fed 'straight' through. So, what you have to do is pull the fabric back a little bit. Make sure to leave enough fabric so you can actually pull it through. Fix the fabric so it's straight and pull it through again. This is actually what I do for both bias tape makers.I like this but I think it's just a bit too narrow for me. I'm actually scared to fold it in half and iron again because it's so narrow. Maybe eventually I'll be able to be brave enough to fold such a narrow piece :P
