I am definitely feeling the love in your cakes! They make me smile. My suggestion would be to try out a variety of frosting tips to see which give you the affect that you are going for. For straight lines you can make a line in the frosting with a tooth pick before you pipe to help give it a straighter appearance. And I like to chill my cakes before I decorate them to give myself a hard surface that is easier to work on. (Sorry I can't figure out how to comment on a photo from my phone). Keep it up!
Thank you so much! I honestly would love to take a class or two when I get a chance. Those cakes are the ONLY cakes I've done, but I love getting advice and I've never thought about using a toothpick to be honest! Thank you! I def. chill my cakes as well and do a crumb coat to seal in crumbs before the actual frosting job..I do a lot of youtube searching and just practice when I can, which really isn't often considering these are the only "decorated" cakes I've done :p They're usually thrown together, but I've gotten lucky :p. Thank you for your kind words again, I really, really appreciate the pointers! Hope you have a wonderful evening!
