in this video we're going to be talking about interfacing interfacing is also known as a stabilizer what it is is a white light piece of fabric that went iron-on to your fabric piece cut out of your pattern once it cools it becomes stiffer this is why it's used for collars or for buttonhole placements and such so the fabric holds up the shape a lot better the heavier grade the interfacing is the stiffer the fabric will become so we're going to be showing you how to apply it here in order to find out how much interface and you need for your pattern you're going to look at the back of your envelope that your pattern came in so this is the back of mine I'm doing the jacket if you look right here it says interfacing one in 380 yards of 22 to 25 inch lightweight fusible so this is good because it tells you how much you need what with usually interfacing is around 20 to 25 inches as usual the same width and then what grade this is going to be lightweight if it would be heavy weights it would say heavyweight or it would say mid weight if you need something medium but this is lightweight so once you know how much and you get that you're they get a consult of directions that come with pattern and this shows you how to lay it out so it shows what pieces need the interfacing we need two of the number five a pattern and we need one of the three which is more likely a collar and then we need one of number six here so this shows you what pieces and then how much you need of each piece this is single thickness so it's not folded in half it doesn't say fold or anything like that so it's just going to be a single layer with your pattern pieces laid out and then we're going to cut out each of these pieces so I have my interfacing laid out here as you can see it's not very wide this is only a single layer of interface and it's not folded in half I fir to started pinning my pattern pieces here your pattern pieces are going to be the same size as the rest of the pattern that you about so if you actually look in your pieces it'll say cut to a fabric cut to of interfacing on it so that's also very helpful I only have one of this pattern piece though and since I really don't have the room to fold its in half I pin one I'm going to cut this out and then I'm going to flip it so it's an exact mirror and put it over on this side the reason why I need to do this is because if you look you'll see these little dots all over on the side these dots is the glue it's only on one side this side is just soft and white and doesn't have any glue on it these little dots when heated will fuse with your fabric so we need one side for one piece of fabric and then the complete opposite for other fabric piece that's also the number five so I'm going to go ahead and cut this one out and we're going to talk about the number three here so here I have my number three pattern which is the collar now this is actually half of the collar is normally placed on the fold of my fabric but in this case I can do that because I don't have enough of interfacing here so what I'm going to do I just loosely pinned it down I'm going to take my fabric marker and I'm going to draw an outline around this whole piece after I've done that I'm then going to take it off get on pin it and take it apart and I'm going to flip it into the other direction in order to create a whole collar so I went ahead and drew to outline where my pattern including the nachos you still need to hack those so you can match them to your fabric piece and now I'm going to flip this over match it up to my end and now I'm going to pin this side so I'm just going to go ahead and keep this on the side pin and after I draw the blue line as my guide and once I cut this out but then I'm going to cut out along the blue line and so I'll have a single uniform piece of collar which is exactly what I need for my project so now I'm going to be applying my interfacing to my fabric piece I have it with the glue side down I lift this up this is the side that has the dots the glue which goes to the wrong side of my fabric piece so this is the right side of my fabric piece this is the wrong side this is the glue side and this is the other side of interfacing so we're just going to sandwich all this together and you're not going to stick any pins in it you just want to very carefully line it up lay it down then you're going to get a piece of white cloth I use an old pillowcase that I have you're going to run into the wallet water then rain it out getting out all the excess water once you've done that you're there I'm going to very carefully lie it down over your piece be sure sure not to move your interfacing your iron you're going to want it to be really hot you're going to put your iron at the setting you would use for the fabric so if you're doing cotton you'd want to do it a pretty hot setting the cotton setting if it's a wool you're going to do is sort of the medium heat so you're just going to make sure that it's at the correct T and then what you're going to do is you're going to take our iron and press firmly over one area of your piece and I would keep it down for about 10 seconds then I'm very carefully to pick that up and move it over to my next area you hear a little sizzling and that's the the water in my pillowcase kind of steaming up warming the glue and my interfacing hopefully fusing with my piece underneath I'm going to move it now I'm going to do this for my whole piece if your cloth starts to dry out we just put it on with the water again and heat it up for a little bit just make sure that it's not soaking wet it's just damp so I did most of it see if it worked and I have to do this corner again but as you can see is pretty much sticking to my fabric here so that's exactly what you want it to do and then you're going to treat it like it's a regular fabric piece that you would just normally just go ahead and sew with so this is going to be part of my collar
