I kept the original name to help you to find the pattern.
The tube is not difficult, but needs time (and patient). A globe is difficult at first time, but after some practise (and understanding the pattern) it becomes easy.
You can find these patterns at many sites, for example at http://www.gyongyvilag.fw.hu/.
The patterns are in Hungarian, but unless you are complete biginner, you will figure out the way of beading.
