Learn how to make a fabric envelope with a free sewing pattern. This beginner sewing project is fun for kids or for Valentine’s day.
Do your kids or grandkids like to play mailman? My kids have always loved playing town and writing and delivering letters to each other. It’s so fun to see them play.
I decided to create an envelope sewing pattern that they can use over and over again while they deliver letters to each other, and I can’t way to use them to decorate for Valentine’s day next year. I made these envelopes basic with floral fabric and basic stamps, but it would be fun to add actual addresses and make the stamps more unique!

What fabric should I use to make an envelope?
The best fabric to use for an envelope is quilting cotton. It’s easy to sew, easy to find, and comes in every color and print imaginable.
These pattern pieces are small enough that you could even use up some fabric scraps!
What interfacing and fleece should I use to make an envelope?
This sewing project uses both lightweight interfacing and fusible fleece. The interfacing adds stability and the fusible fleece adds cushion. The cushion is not needed, it just adds an extra element of texture and interest to the envelope.
What closure should I use on the envelope?
You can use buttons and buttonholes, Velcro, or plastic snaps. I used plastic snaps because they are so quick and easy to install, and they come in lots of fun colors.
Can I add an address to the envelope?
Yes! That would add such a fun element to the envelope. I suggest using free motion quilting to “write” the words or to use a cutting machine and iron-on vinyl.
What is a PDF sewing pattern?
A PDF pattern is a sewing pattern designed on the computer and organized so that it can be printed on several letter or A4 size pieces of paper.
I love using PDF sewing patterns because if the pattern gets ruined or if my children or I changed sizes, I can always print it again. It’ll never be destroyed since I have a digital version!
How do you use a PDF sewing pattern?
Open the PDF on a computer and click print. When printing make sure that the scaling is set to 100% or no scaling so that the pattern prints at the correct size.
Once the pattern is printed it can be taped together to get the full size. Then the pattern can be cut for each pattern piece size or individual sizes can be traced so that the pattern can be used again and again. Learn how to use PDF sewing patterns.

Cut out two fabric pieces, one fusible fleece piece, and one piece of interfacing. Optional: Cut out a 1 inch by 1 inch piece of fabric or piece of felt for the stamp.
Iron the interfacing onto the back of one piece of fabric. Iron the fusible fleece onto the back of the other piece of fabric.
If you are using fabric to make the stamp, add lightweight interfacing to the back.
Pin the stamp fabric to one of the envelope pieces 3/4 inch from the side and upper fold. Sew in place with a zigzag stitch.
Pin the envelope pieces right sides together.
Sew around the envelope with a 3/8 inch seam allowance. Pivot at the corners and backstitch when you start and stop. Leave a 3 inch hole to turn it right side out.
Trim the corners that point out and clip the corners that point in.
Turn the envelope right side out through the hole. Carefully poke out the corners.
Press the envelope flat. Make sure the seam allowance of the hole is tucked inside when you iron it.
Edgestitch around the whole envelope.
Bring the bottom edge up on the foldline. Clip it in place.
Sew the two sides to secure the envelope pocket. Backstitch when you start and when you stop.
Add snaps to the flap and to front of the envelope. You finished!
