How To Apply Wonder Under // Clear and Simple Tips & Tricks
Wonder Under is a great little product that comes in handy for many sewing and crafting projects.
In this post, I’m going to show you some simple tips & tricks on how to use this fusible webbing that you might find helpful. I’ll show you the basic application, which is super easy.
What is Wonder Under?
You may not have even heard about Wonder under or fusible webbing. It’s basically a thin webbed piece of glue that has a paper backing. It’s used to adhere one piece of material, like fabric, to another material.
You can wash whatever you put it on and it will stay on there. There are a couple of different brands and types of fusible webbing. I really like this Pellon brand. It also comes in a brand called Heat n Bond that works well too.
You can get it in a lightweight and ultra hold that works for something that you’re maybe going to be washing all the time. It comes in the store by the yard or in packages, and can also be found online.

How To Apply Wonder Under
Decide what shape, fabric design, or letter you want to use as a cutout iron-on.
****NOTE: Whatever you are cutting out will be “MIRROR IMAGED” when ironing it on. For example, the letter “J” needs to be cut out backward, whereas a symmetrical shape like a heart would not.
1- Cut out a piece of fabric a little bigger than the shape you will be cutting out.
Place the fabric RIGHT SIDE FACING DOWN. Then cut out a piece of Wonder Under the same size.
Set the fusible sheet aside for now.
2 – Tracing the design
Trace the design onto a regular sheet of paper. If you have a lightbox use that. However, if you don’t, no worries, just go to a window and tape the paper to the window and place the Wonder Under paper over the top and trace away.
Once you have your letter traced, put the Wonder Under paper over the reversed letter and trace it.
3 – Wonder Under application
Set your iron on the high setting and make sure the steam is off. You’ll use a dry iron.
I love using this table ironing board for small projects like this.
Take the webbing sheet and place it down on top of the fabric. Then place the backward “J” paper on top of the webbing. The traced paper needs to be bigger than the webbing!
If the webbing is sticking out at all, and you press it, you’ll have a BIG MESS on your iron and you don’t want that. Then the next thing you press will have goobers on it. (See my hack for getting that muck off your iron).
When all the layers are in place, simply press it for about 10 to 15 seconds you don’t want to overdo it because you’ll burn the glue. Let it cool and then cut around your shape.
4 – Peel off the paper backing
The next thing you’re going to do is peel off the paper backing.
This can be a REAL CHALLENGE sometimes because it’s hard to separate the paper from the fabric. BUT NO WORRIES. I have a simple hack that is a LIFE SAVE! (For those of you who have struggled with this, you’re going to love this)!
Take a simple pin and make a little X in the middle of your shape somewhere. Score the paper and the paper will pop out a bit and it will give you something to grab and pull, which is a heck of a lot easier.
The back side of the fabric will have a little rubbery plastic texture now.

5 – Applying the shape
Take your letter or shape and place it right side facing up and press in place.
Applique Stitching
If you have an item that is going to be washed a lot, you may want to do some satin stitching (applique) which is basically a very short-length zigzag stitch around that item. This will help it so it doesn’t come off.
Set your sewing machine to a zigzag stitch, the width at 4 and the length at 0.5 to 0.7.
I recommend testing the stitch on a scrap piece so you can see if you like the stitch. You want to have the outside of the zigzag stitch be right on the outer edge of the applique.
Take the hand wheel of your sewing machine and turn it towards you to bring the needle down so you can see where the stitching is going to be.
Sew around the shape, taking your time around corners and curves. You may need to stop and lift up the presser foot to adjust around corners.
That’s it. Now you have an applique that is secure and won’t fall off after washing.
I hope you found this helpful.

Make sure to label your bottle! There have been so many times that I mix up some brew and forget what is in the bottle. 
I have these labels available in my shop
2- When my washcloths and hand towels get old and ratty, I repurpose them as cleaning cloths. If you want to get really organized, you can buy a set of inexpensive washcloths at Walmart that are all the same color. That way you know what are cleaning clothes and which ones you’ll be using on your face.
