I use a Xyron sticker maker to get the images to stick. I tried blowing through the straw yesterday to get the bubbles out and it worked for some, but there were still a lot of bubbles in them. Definitely use a lighter for them. I've been making a lot of singed flowers lately, so all of my grill lighters were all out of lighter fluid! And I didn't think about that before I started!!
I only made a batch of 12, but they all got ruined! Argh!!! I got hubby to buy some grill lighters last night, so i gonna try it again!
