Step 1: Gather Materials
You will need: sewing machine, scissors, thread, straight pins, one standard pillow (used by a person your dog likes immensely), and one men's fleece jacket with a front zipper (size L/XL).
Step 2: Cutting
Cut collar and arms off fleece jacket, leaving the complete zipper (you'll just sew around this and stuff it back inside when the project is complete). Cut open one sleeve down the seam, cutting off the seam edge. Note: Keep the zipper zipped until Step 6.
Step 3: Getting the Proper Size
Place pillow on the cut-up jacket to get the proper size for the pillow cover. I used the front and the cut open sleeve to make the top/bottom of the pillowcase. Work from the bottom of the fleece jacket front so you will only have one end of the zipper to deal with - you don't want to cut any of the zipper. (The zipper from the front will face the floor and be the opening for putting the pillow into the snuggley). Cut the fleece slightly larger than the pillow, allowing for seams and for the thickness of the pillow.
Step 4: Cutting the "Flap'
Cut the back of the fleece jacket larger than the other two pieces; this is necessary to allow the dog to fit into the space and have some room to be comfortable while resting. This will look like an additional piece of fabric attached to the pillowcase, henceforth called a "flap" - open on one side to allow the dog to enter.
Step 5: Organizing Pieces to Sew
This step just takes a little bit of thinking through - laying it out to put together. Lay the front of the jacket - now the bottom of the pillowcase (Snuggley) , zipper face down. Next lay the sleeve - now the top of the pillowcase (Snuggley) on top. Flip pieces so that wrong sides are facing out. Sew these two pieces together - down one side only- making a small seam that will be on the inside of the pillow case.
Now the "flap" is the final layer. Because it is larger, you will need to make tucks to make it fit the top of the Snuggley. Pin the top "flap" to the top of the pillowcase making the tucks to make it fit. Remember to only do this on 3 sides - the 4th is open. To make this easier, leave the open side of the "flap" on the same side as the seam you just made.
Now for the final stet in sewing. Turn the top of the pillowcase(with the flap pinned properly to it) and the bottom of the pillow case inside out and sew the other 3 sides together. You will have to re-pin. Also, the zipper will need to be taken into consideration. I just stopped sewing when I came to it and started again after it. Since this is fairly thick, I used a size 14 needle. No need to worry about hemming as fleece does not fray.
Step 6: Placing the Pillow
Turn your Snuggley right side out. You will have to unzip the zipper to do this. Put your pillow into the pillowcase of the Snuggley. Zip it up and stuff the zipper into the "hole" was left because you didn't sew across the zipper.
Step 7: Introduce Your Dog and the Snuggley
Show your dog his/her new bed. You will be delighted at how much they love it and the easy care of washing and drying it for them.
