I make felt food and for starters I would highly recommend making templates/patterns out of paper to start with.
For making round shaped foods (like this
cake I made), that will require sides (not flat like a cookie), the best way to do this is to trace a round object (like a mug) on paper - cut out. Then take a piece of yarn, and guide it around the border of the cut out circle, mark and cut the yarn - you know have the length you'll need to go around.
Then measure and/or lay the yarn out on a piece of paper to cut as the side piece - this should give you two matching pieces to work with now: circle for top and botton (cut 2), and a rectangle to be the side.
Pin to felt with straight pins, then cut and sew them up. I also recommend a site that will give visual tutorials of the basic stitches like "whip" and "blanket." There are a lot of helpful sites out there - just google the stitch names.
Once you get the hang of it, the possibilities are endless.
Hope this little bit of info helps you get started!
