Step 2: Cut your foam to fit snugly into the crib.
I initially cut the foam to 30 in x 15 in, knowing that I would need to trim it down a little to fit. I then set the cirb mattress pad on top of the crib and used a Sharpie to mark where I needed to round the corners and/or cut off a little foam. The final dimensions were 30 in x 14 1/2 in.
Again, make sure the fit in the crib is snug. Safety first(!) when it comes to the kids!
Step 3: Pin your vinyl around the cirb mattress pad.
Place your cirb mattress pad on a single layer of vinyl (vinyl is located in the 'utility' fabrics area of your local craft store - available in many colors). Make sure you have a buffer around the outside of the foam - 2 or 3 inches is sufficient.
Fold the vinyl over the cirb mattress pad, tightening the vinyl against the foam on the folded side (creating a vinyl-foam ...taco?).
Pin the top layer of vinyl to the bottom layer of vinyl around the foam. Try to get your pins as close to the foam as possible for a tight fit.
Cut off the excess vinyl.
Step 4: Sew around the cirb mattress pad.
Top-stitch around the three open sides, as close to the cirb mattress pad as you can get. You may need to squish the foam down a bit as you go.
Note: If you're wondering why I only pinned/sewed three sides here, the reason is that I am inherently lazy and cheap. The less work I have to do and the least amount of materials I have to use, the better. You could, indeed, pin/sew all the way around (you masochist, you).
Step 5: Make vinyl binding.
You'll need to make some binding to hide your raw edges. Cut 2 inch strips from your leftover vinyl - enough to cover all your edges.
If you need to sew several strips together, here's how to do it:
Place the two pieces perpendicular to each other at their ends. Sew across the two pieces at a diagonal.
Cut off the excess.
Fold open. Repeat if needed.
