 Mouse House 

 

Back to Table of Contents

 

1 Small photo album

 

(photo album with rings designed to hold a single 4"x6" or 8"x10" picture on each page is a good size).

 

2 Soft sponges

 

Double-sided carpet tape

 

1 Hot glue stick

 

Stick Tack or putty used to hold pictures on a wall

 

8" fuzzy (female) adhesive-backed Velcro

 

1" Hook (male) adhesive-backed Velcro

Mouse House

Supplies Needed 

Back to Table of Contents

 

Remove the pages from the photo album.

 

Place the two sponges side-by-side.

 Place the mouse on the two sponges diagonally and trace around the mouse.

 

Cut out the area of the sponges where you traced the mouse. This is where you will place the mouse.

 

  

 

 Cut a notch in the sponge to hold the USB connection wire as it runs off the back edge of the sponge. See photo.

 

 

 

Mouse House

Instructions 

 

Place the double sided tape on the back of

the sponges and affix them to the inside back cover of the photo album. Make sure the sponges are placed together so the part removed will hold the mouse firmly in place.

 

 

 

 

 

 

 

Place the mouse in the opening cut in the sponges and lay the USB wire in the notch so the connection is by the album rings.

 

 

 

 

 

 

 

 

Back to Table of Contents

 

 

Cut a short piece of the glue stick with scissors. The size will vary with the size of the photo album rings and mouse. I used an album with inch-and-a-half rings and a 3/4 inch piece of glue stick. 

 

 Using the stick tack or other putty fasten the short piece of glue stick to the inside front cover of the photo album so that it will activate the mouse button when the photo album cover is closed over the mouse. Multiple attempts may be necessary to position the glue stick.

 

 

 

Mouse House

Instructions 

 

 

Remove  the backing from the 8-inch piece of adhesive backed looped (female) velcro. Fold the Velcro in half, adhering approximately 3-inches of the Velcro together. The 1-inch not doubled should be adhered to the top and bottom of the front cover of the photo album to form a tab. Affix the 1-inch piece of hook Velcro  to the back cover of the photo album in alignment with the tab created on the front cover.
