I will eventually do a step-by-step tutorial and add it to the hammock tutorial pdf, but for the most part, these instructions are simple (the same premise as a flat hammock) and the hardest part is figuring out the dimensions - especially for levels that have a cut-out for the ramp.
A Dual Critter Nation will require one bottom liner, one top liner, and two shelf liners. Each liner will need one piece of fleece and one piece of furniture cloth, cut to the following dimensions:
A Martin's R695 will also require one bottom liner, one top liner, and two shelf liners. Each liner will need one piece of fleece and one piece of furniture pad, cut to the following dimensions:
|The Martin's Bottom Liner is sized a little long so the|
cage sits on top and secures the liner to the floor.
Note that when the liner is not a perfect rectangle, but has a notch cut out, you will need to make sure to cut the fleece piece as shown with the right side up. This should match the layout of the shelf or level. (The furniture pad has no right and wrong side, but if it did, you would cut it as shown with the wrong side up.)
To sew the liner, pin the fleece to the furniture pad, right sides together, wrong side out. If it is a notched liner, the layout will look wrong with respect to the layout of the actual level, but after it is sewn and turned right side out, it will look right again.
Sew along all edges of the liner with a 1/2" seam allowance, leaving an opening large enough to turn the liner right side out. Trim the excess seam allowances, and turn the liner right side out. Push out the corners and flatten to the proper shape.
Slip stitch the opening closed by hand (or machine stitch it closed very near the edge), then top stitch around the entire liner to hold the proper shape.

Secure CN Liners
The Martin's bottom liner sits in the bottom pan. Because it is a little longer than the cage itself, the weight of the cage on top of the liner will hold it securely in place. The Martin's top level liner should stay in place by itself, being held in place by the surrounding cage walls. However, if you would like, a large binder clip can secure the liner in place at the ramp opening. Shelf liners can also be held in place with a large binder clip. Alternatively, you can install grommets in the corners of the top level and shelf liners, place a split ring through each grommet, and a lanyard hook in the split ring. The lanyard hooks can then be clipped to the cage wall to secure the liner in place.
The one thing I might try a little differently with the Critter Nation liners, since the corners of the pans are slightly curved, in the outer four corners, instead of doing an angular corner, sew a slight arc, so the corner point doesn't stick up as much.
