How to make a Tunnel Bridge!

Posted by Summer Wright on

This tutorial will show you how to make a Tunnel Bridge. These bridges are great because they have a 'tunnel' sewn underneath where pets can play, eat, and sleep. Example size will be given below, but it can be made larger easily by adding a couple inches to each side.

Supplies needed:

-Sewing Machine(here's the one I use)
-Rotary Cutter or Scissors
*Fabric pen or chalk to mark cut lines
*Pins or clips
*C-Links to hang items

*Optional supplies

Fabric Needed:

Fleece Solids:

  • One 8" x 15" piece
  • One 9" x 11" piece

-Fleece Prints:

  • One 8" x 15" piece
  • One 9" x 11" piece

-Hanging Tabs

  • Four 1" x 4" strips of fleece

If you don't know which side of fleece is the 'right' side, hold the fabric so it stretches across, then pull slightly. The edges of the fabric will curl towards the 'wrong' side. 

Step One:

First, cut and gather your fleece. The longer, thinner pieces will be your "bridge", while the shorter, wider pieces will be your "tunnel". Pair the prints and solids together on the "tunnel" piece, making sure the right sides are facing each other.


Step two:

Grab your "tunnel" piece, and sew the longer sides together, like pictured. Then flip the piece inside out so that the seams are on the inside.


Step three:

Grab the print for your "bridge" piece and lay in down on your table, with the print facing up. Lay your "tunnel" piece down on top of it, folding it over a bit so the open ends of the "tunnel" piece line up with the longer sides of the "bridge" piece.

Note: Make sure the prints are facing together, so that the prints will all be on the outside once everything is finished.



Step four:

Lay your solid "bridge" piece over the others, with the right side facing down. Carefully line up the edges, and pin or clip it to keep everything in place.


Step five:

Sew all the way around, making sure to include your 4 hanging tabs. Leave a 1-2 inch opening to flip everything.

Tip: Rather than putting the tabs right in the corners, try putting them about an inch away from the corners, then sewing around them. Just make sure they're far enough away that you don't accidentally sew the tab into the side.

To make the tabs: Fold your strips in half to make them loops, then line up the open ends with the edge of where you're sewing.

Step six:

Just flip everything through the opening you left, then sew the opening closed, and you're finished!

  • Am I missing something? I don’t see instructions for the tunnel opening that you would need something circular To trace which is under description?
    I live the pattern …. thank you

  • I’m curious… if you don’t mind me asking- what is your cage made out of?

  • So I made two of these tunnel bridges and I love the idea. My gliders love their tunnel and I figured this would be great for them. I did find that the tunnel portion is a little to wide once made. My gliders like a tiger space in their tunnel. I think I am going to try one with the bridge part cut to a 9”x 13” and the tunnel part being a 8” x 10” that way the bridge part is longer and the tunnel is a little tighter. The pattern is easy to sew and I love the idea. Thanks.
