Mary...
Be thankful for what they have done for you in the past. But this is now... and it's time for you to enjoy a new found passion. Yes, you will want to buy a piece of fabric that you just can't live without... if you have the money at the time and it won't affect anything else... go for it. Also... keep your eyes open at garage sales and flea markets. Sometimes you can get a tremendous buy for next to nothing.
