A plain sweatshirt is the best blank canvas in your closet. A few patches and some embroidery thread can turn a five dollar thrift find into something that looks boutique made.
You do not need to sew clothes from scratch. You just add character to something that already fits well, which makes this one of the most beginner friendly fabric projects there is.
These 15 patchwork sweatshirt DIY ideas cover the basic supplies, simple techniques and fun designs for every season.
1Start with a Good Blank Sweatshirt
The base sweatshirt matters more than you would think. Thin, stretchy fabric puckers under patches, while a medium or heavy weight cotton blend stays smooth.
A blank crewneck sweatshirt in a neutral color lets the patches shine. Wash and dry it once before adding anything, so it does not shrink afterward.
- Smooth base
- No surprise shrinking
- Neutral canvas
My Pick
Blank Crewneck Sweatshirt
A good weight, plain sweatshirt that makes every patch look intentional.
2Attach Iron On Patches
Iron on patches are the easiest way to start. No needle, no sewing machine, just heat and pressure.
A variety pack of iron on patches gives you room to experiment. Here is how to make them actually stay on.
- No sewing needed
- Beginner friendly
- Quick results
Project Card · 20 minutes · Easy
Materials Needed
- Prewashed sweatshirt
- Iron on patches
- Household iron (no steam)
- Thin cotton pressing cloth
- Ironing board
How to Make It
- Lay the sweatshirt flat and arrange the patches until you like the layout.
- Set the iron to the cotton setting and turn steam off.
- Cover one patch with the pressing cloth and press firmly for about 30 seconds without moving the iron around.
- Turn the sweatshirt inside out and press the back of the patch area for another 20 seconds.
- Let it cool completely before checking the edges, then press again if any lift.
PRO TIP Wash patched sweatshirts inside out on cold and skip the hot dryer. Heat and tumbling are what loosen iron on glue over time.
My Pick
Iron On Fabric Patches
A big variety pack so you can play with layouts before you commit.
3Make Patches from Any Fabric Scrap
Fusible adhesive lets you turn any fabric scrap into a patch. Old shirts, quilting cotton, even a favorite worn out pair of pajamas.
It opens up endless designs, because you are no longer limited to store bought patches.
- Use any fabric
- Endless designs
- Upcycles scraps
Project Card · 30 minutes · Easy
Materials Needed
- Fabric scraps
- Paper backed fusible web
- Pencil and scissors
- Iron
- Pressing cloth
How to Make It
- Draw your shape in reverse on the paper side of the fusible web.
- Iron the rough side of the web onto the back of your fabric scrap.
- Cut out the shape along your drawn line.
- Peel off the paper backing.
- Place the shape on the sweatshirt, cover with a pressing cloth and press firmly until it bonds.
PRO TIP Draw letters and numbers backwards on the paper side. It feels odd, but they come out the right way round on the sweatshirt.
My Pick
Fusible Fabric Adhesive
Turns any fabric scrap into an iron on patch with just heat.
4Stitch Edges with Embroidery Thread
A simple stitched edge makes a patch look more finished and helps it stay on through many washes. Matching thread blends in, contrasting thread becomes a detail.
An embroidery thread set gives you every color you need. Here is the easy blanket stitch I use on almost every patch.
- Finished look
- Stronger hold
- Pretty detail
Project Card · 30 minutes · Easy
Materials Needed
- Embroidery thread
- Embroidery needle
- Scissors
- A patched sweatshirt
How to Make It
- Thread the needle with two or three strands and knot the end.
- Bring the needle up from inside the sweatshirt, just beside the patch edge.
- Push the needle down through the patch about 1/4 inch in from the edge.
- Bring it back up at the edge, passing the needle over the loop of thread before pulling tight.
- Repeat evenly around the patch, then knot the thread inside the sweatshirt.
PRO TIP Put a piece of cardboard inside the sweatshirt while you stitch. It stops you sewing the front to the back by accident.
My Pick
Embroidery Thread Set
Every color you need for stitched edges that look neat and keep patches secure.
