I looked here on CC and on the web and I can't find any directions.
How would I pipe small pumpkins. I'm doing a cake for a party and need to pipe a small pumpkin on each square slice, like they do on carrot cakes sometimes.

Try experimenting with your different star tips. I made a couple with a tip 199, just piped like a really fat dot:

Totally different than I was picturing, but still super cute. (I was thinking like a frontal view.) I'll play with that. Thanks!

Just make balls - tall ones, round ones, whatever you want using a plain writing tip (ie:6-10 or 12) or star tip.
Hold the bag straight up & down; squeeze, and pull away straight up. Add a tip 2 or 3 green or brown stem.

I like to make pumpkins by using a round tip, size will depend on how big you want the pumpkin. I make two parentheses shapes, a left and a right one, then both again slightly overlapping towards the center. If these inner two are close enough, then just one down the center to finish it off. I'm pretty sure this doesn't make sense, so I'll try to attach a picture with this message and you'll see the little pumpkins I made. I think I used tip #8 for them.

Thanks everyone!
Maisy, those are exactly like I was picturing and your description made perfect sense.
