With all the problems I keep having that the pages of this site won't completely load for me I cannot see any of these creatons
Something I have often told my students is to take a day and ONE tip - say today's tip is 102. Now do *every* technique you know with that tip. Dots, stars, zigzag, shells and/or whatever. Now give the tip a 1/2 turn and do it all again. Some tips don't lend themselves to turning - they are the same no matter how you hold them like rounds & star tips but others will give you a completely different look.
See what you can design that is different & unique
The other tip is to get yourself a copy of "the Wilton Way of Cake Decorating" Volume 3 - often called a complete Encyclopedia. It's out of print but often available on eBay. There are pages and pages of wonderful ideas in it on making flowers and borders.
