Hey, strangers…it’s been a while!  I’ve been giving myself a bit of an extended blogging break as I navigate the waters as a mama of three. It made me a little sad to miss out on blogging fun Thanksgiving and Christmas projects, but it’s also been refreshing to just take a bit of a step back. I’ll be back to create content and publish new posts as I can – as inspiration strikes and I get a little bit of time to actually photograph and write about it – but in the meantime, there’s a slew of inspiration in my project gallery from years past! (I just hit my 6 year blog-iversary, isn’t that crazy!?). In any case, I got a chance to whip up this adorable Little Sweetheart Valentine’s Onesie yesterday and I even had time to photograph it (!!), so I’m excited to be able to share it with you. Psst – there’s a free cut file, too!

I’ve been practicing my lettering and doodling with my iPad Pro + Apple Pencil + the Procreate App when I get a chance (which is rare), and this design just sort of took shape out of a practice doodle. I figured it would make an adorable Valentine’s onesie for my 4 month old (how is she FOUR months old already, by the way??), so I turned it into a cut file to use with my Silhouette. You can, too!

“Little Sweetheart” Valentine’s Onesie Cut File – Tutorial

This is a really simple design to cut, weed, and apply! First things first, after you’ve opened the file in your design software and sized it how you like, mirror your design. (Remember that HTV is cut on the back side of the material, so you have to cut a mirror image of how you want your design to appear on your shirt.) If you want to cut it all out of one color, you’re set to go! If you’d like to do it the way I did – with the script words and hearts in one color and “SWEET” in another, you’ll need to ungroup your design and cut them out separately on each color. Normally, I’m all for saving vinyl and filling in empty spaces of designs…but for this one, I’d recommend leaving the spacing as-is between the script words where “SWEET” will go and just weeding the excess out. It will make lining up your design a lot easier!

Start with the script words and place it on your onesie where you’d like it to go. Use your iron, EasyPress, or heat press to adhere it to the onesie. (If you’re using an iron, make sure to use lots of pressure and patience!)  Once it’s adhered, peel up the carrier sheet and place the “SWEET” in the middle – it shouldn’t overlap any of the design you’ve already ironed on. Before you begin to press or iron, make sure to put a carrier sheet down! I use these teflon sheets and they’re great. You could also use a thin dish cloth or t-shirt. Just make sure the heat of your iron or press doesn’t touch the uncovered HTV!

Simple as that, and it’s done! So cute, isn’t it? It will be even cuter on our little sweet heart herself. <3
