Medicare allows for mask cushion replacement every three (3) months, and a complete mask system replacement every six (6) months. CPAP manufacturers and vendors suggest these replacement schedules as well. In our experience, most mask cushions begin to deteriorate after about six months of use.
Hereâs what you do: 1  Figure out the length that you want your finished sleeve to be. On the outside of the shirt, mark that spot with a line. 2  Using a see-through ruler or regular ruler, mark a line 1 Â½â underneath the first line. Use the ruler to continue that line across the sleeve. 3  Repeat on the other sleeve.  Cut on the second line you drew.
I rarely see shirts/dresses with tulip sleeves so it would be a pretty unique addition to your sewing project. They look cool and are simple to make. Start by tracing your sleeve piece twice. Make sure to transfer markings. On one piece draw a curved line extending from the left side of the sleeve cap to the hem. On the other piece do the same starting from the right side of the sleeve cap.
