Well my oxygen concentrator finally arrived and I love it! Been busy practicing and teaching my girls what I know...It's so nice that they are so interested. I have decided to set up a schedual of techniques and work my butt off till I get the hang of each one. So far I have gotten pretty good at a regular round shape with nice puckered ends, and I'm getting much better with encasing. I have made myself a bracelet using my beads..here it is.
