Good points and ideas Quirky.
I just changed the banner yesterday. Along with the blog title, it used to say "free activity & coloring pages, arts & crafts pages, nurturing creative minds with fun activities". There were no images, when I added the images I changed what the header said. Also, since I started, I added video links as well as recipes, so the banner got to be too cluttered. Have the navigation bar up now, didn't have time to do it last night.
I didn't have the Archive up until yesterday, I just added that because I didn't have time to to the navigation bar. I have deleted that when I added the nav bar.
I check my screen resolution with my mouse, I have the roll, clicky thing, hold ctrl key and roll one way to make screen bigger the other to make it smaller.
as far as the stretch, I think you have a much wider screen than I do and I always work with my bookmark sidebar open. I guess I always work to make sure everything fits on a smaller screen than on a larger.
All my blogs are the stretch template, I am going to try to find a way to reduce the stretch so it doesn't take up the whole screen if they have a large screen.
As far as the colors, my 8 yr old and 6 yr old picked them out...this is actually "their" blog. The really wanted to go wild with the colors lol and this is what we settled on. This is the toned down version. Many of the kids coloring pages are very colorful, bright and flashy. I am trying to attract children, so I had children help with the design.
When we start adding our own activities, recipes, even videos I will include pictures with them and they will be added to the sidebars.
