Smooth Rounded Edges on Flat Polymer Clay Cutouts

Using Glad Wrap To Get Round Edge Cutouts - Polymer Clay TutorVideo #620: All you need is some plastic wrap and a cookie cutter to get professional looking edges every time.

Topics Covered In This Video:

  • I’m going to show you a super easy way to cut rounded edges on your polymer clay pieces, using cookie cutters and plastic wrap.
  • Here is the difference between two polymer clay pieces cut out with a clay cutter… one is cut out normally and has straight or squared off edges.
  • The other one was cutout using plastic wrap, and it has has rounded or beveled edges.
  • Both look cool… and both have their purpose.
  • The rounded edged one has a special, pillowy look to it.
  • It works for larger cutters as well as small ones.
  • Let me show you how easy it is to do.
  • Those of you who have been around our blog for a while will already know this trick, but there are many new people coming every day that may not know it, so I thought I would share this tip with you today.
  • Roll out a sheet of polymer clay any thickness. Mine was at thickest setting of 8 playing cards thick and then doubled over the sheet of clay.
  • It doesn’t matter what thickness you use, but the look will be more obvious on the thicker pieces.
  • Smooth out the top of your clay sheet to remove any surface flaws or imperfections.
  • Use a section of plastic wrap to cover the clay surface.
  • I used Glad Cling Wrap because it is compatible with polymer clay, but since the wrap has such a short contact time with the clay, that compatibility issue is not too critical for little trick.
  • Some plastic wraps react badly with polymer clay and should not be used long term.
  • Make sure your plastic wrap is pulled tightly on the surface of the clay, with no wrinkles or air pockets.
  • Use cookie cutters or clay cutters to cut out desired design, pushing down through plastic wrap and clay together, all in one downward motion.
  • Plastic wrap will follow the edges of the cutter, and pull the clay down… rounding the edges.
  • The plastic wrap also keeps the clay from sticking inside of cutters, which can be a problem especially for the small cutters.
  • Remove the cutter and pull off the plastic wrap from the surface of the clay and Voila!… A polymer clay cutout piece with perfectly rounded edges and a flawless surface. So easy!

    Good reminder Cindy, one of the best tips you taught us!

    I have been searching for a tutorial on an Awareness Ribbon Cane. It would be great if you have such a tutorial. I work with families of children fighting Childhood cancers and they are always looking for awareness items to support their kids.

    An awareness cane is a good idea Diane. I’ll see if I can add that to the list!

  4. Dixie Ann, 30 January, 2015

    Hi Diane, you can make awareness ribbons without making a cane. Just cut strips of whatever color clay you want, form them into a ribbon, decorate and then bake. This way you can make any size or color you want. Hope that helps.

    I have been watching your videos for a while and always love your advice. I create heartpasses in memory of my mum and know this will help give me an even better finished heart. You are making a big difference in the Polymer Clay world. Thank you again!

    I would love your address so I could send you a heart to pass on in kindness.

    Have an awesome day!

    Hi Bonnie, that sounds lovely, thank you! I just sent my mailing address to you via email.

    I have used this technique and it is a good idea. My memory is such that if a tool isn’t right in front of me I forget to use it.

    I have a general question: My oven only heats for 30 min. and then turns off. I don’t have it right next to me so I have to get up and turn it back on for another 30 min. Has anyone rigged their oven so it will go for an hour? I’ve thought about wedging something under the timer but thought I should wait in case someone else did it and it was a disaster. It’s not a huge problem but sometimes when I’m in the zone, just getting up and crossing the room is enough to trow me off. My only other alternative is to take a gift card I got for Xmas and add a few sheckels and get a toaster oven that has the feature that turns off the timer. I can always use my retired tablet as a timer.

  9. Cindy Lietz, 30 January, 2015

    That sounds like a total pain Peg! There probably is a way to disengage the timer but I don’t know how to do that. If you’re looking to get a new oven, I sure love my Kitchenaid Convection Oven! And it has a timer that goes for an whole hour! :)

  10. Dixie Ann, 30 January, 2015

    Peg, I agree with Cindy. I would not try to mess with the timer, you could end up getting an electrical shock. Cindy and I both have a Kitchenaid Toaster oven and if you live in the states, bedbathandbeyond have the best deal on one with their 20% off coupon they put out often. Good Luck Sweetie.

    fantastic tip, thank you :) I’ve been doing this & it’s awesome!! I laughed when you mentioned some types of Sarah wrap make it sticky etc. I have examples! I also found that fruit & veggie produce bags are awesome for wrapping clay & storing. I cut the bag to desired sz on side without ink and use.. So far it hasn’t made my clay funky.. Yay :)
