I agree with you, your aunt would be pleased to see you using what she left you. What to do with the creations is a good question... I haven't really been seriously into this too long. Bought my own machine just 1-1/2 years ago. But I have been keeping busy since then.
I found Quilts or Kids and I love that organization and I get a lot of practice making those quilts. Quilts for Kids sends me the kits for free (I have to pay postage to my house and to return the completed quilts). All I have to provide is my time, thread and batting - the fabric and pattern is shipped free of charge.
I have made some quilts for my family... and I will probably keep making them.
