How to Pipe a Rose with Buttercream Frosting

Use these simple steps to professionally add a buttercream rose. You'll need a spatula, rose tips, a leaf tip, couplers, a flower nail, a rubber spatula, and piping bags. Begin by squeezing cream onto the flower nail in a circular motion, creating a lump with a tip on it. To create the layers of a rose, squeeze cream in an short arch motion and continue rotating the rose until you have the desired amount of layers, or petals.

    Works relatively well worth compatible surfaces in need of coupling. The plastic / material used is quite strong and well sufficient for basic needs. I would recommend this product.
    Great price on these couplers. Ateco is less expensive than others and easy to use.. they are also easy to clean. So pleased with the quick delivery of my products.
    Having a bunch of couplers around is so helpful and these are great. You can't beat the price on these and they are dishwasher safe.
    LOVE this product. This makes frosting and decorating a breeze. Fit the bag with this coupler and you can change the tips out as many times as you want without having to fuss with a separate piping bag each time.
    These Ateco couplers are great quality, great price and are a solid piece without the "notch" that other brands have...which makes them good to use to pipe even without a tip.
    Essential tool for cake decorating when you want to use a few different tips with the same icing. Will not fit the bigger tips so will need to get the medium coupler if using larger decorating tips.
    These are the perfect couplers to use when you need to change tips frequently. I use them for frosting cookies, and it makes it so easy to switch tips between the different sizes I need to use!
    Great coupler. Still going strong after many, many uses.makes for quick work in changing tips. Will buy again when/if this one ever wears out! Very impressed.
    I love these couplers from Ateco! I used to only use the Wilton brand, but those have gotten brittle over the years and just don't seem as well made. These are made from a harder plastic and really go on smoothly and don't get stuck. I'm actually working on replacing all of my old ones with these because I like them so much!
    I love these piping couplers they are great quality and make decorating cakes so much easier they are very sturdy and make switching tips up super easy!
    These couplers are perfect! They are standard size and much easier to wash than the Wilton ones. I love these!! They do not stain at all!!
    a friend recommended the aetco brand icing bags and couplers to me as im just learning and they are cheap.they seem to be a good grade and were easy to use
    The ateco 2 piece standard coupler is great when decorating cakes. You can make different designs by changing the tips. Easy to use and durable.
    If you like doing fancy shapes on your pastries you need a good coupler to tighten your bag and tip, and this item is a good one
    I love these couplers. Easy to use. My only problem is, I should have order 3 or 4 of the small ones. guess my next order will be a few more
    Great couplers for piping. Coupler came as expected and I use them for cupcakes and cakes etc, I work with a lot of tips and they are easy to wash!
    Always a must have. if you pipe anything just grab a couple of these because they are cheap and durable. great for work or home,
    This plastic coupler are now a staple in our kitchen; these work great with any brand of pastry bags, we use plastic coated canvas, several sizes and these couplers work like a charm.
    these are great for standard size tips. i do recommend purchasing more than you think you need due to misplaced parts after washing. they save me money so i do not need to use multiple piping bags for one color buttercream.
    Very good quality standard plastic coupler . Works really good with the tips that are the stander size. I like this item and used it already.
