I work full time (80-115 hours every 2 weeks) and when i'm not at work...i'm in the sewing room.
i take hand work to work with me...you'd be surprised how much you can get done in 10-15 minute breaks. i can bind a quilt in no time when i work on it during breaks at work. lots of prep work can be accomplished during breaks too, like copying appliques, or drawing diagnal lines on squares for half square triangles. i trouble shoot in my sleep...you'd be amazed at how i've managed to work out a design problem in my sleep :)
Nancy Zeiman put out a book (quite a few years ago) called 5-10-15 minutes to quilt... basically, to find time you just have to take the time...
i don't watch much tv, when the rest of the house is watching that favorite show i'm in sewing...going somewhere this weekend? while hubby is in shower, i'm in sewing room...i 'steal' what ever moments there are...i could decide that i don't have time, but then the time is just spent on some other activity...just decide what you can change to give yourself time....if you take prep work with you to work, then when you get home that part is done, you can sit down at the machine and sew...
time organization is as important (and as hard to accomplish) as any organization in our lives.
