I have a sister in-law who praises my craft skills to the sky and back - and then asks me to make her something She has said "if you ever make me a quilt I'd like it to be ...." or she says "if you ever got around to making a dress for me i'd like ... " I appreciate her loving praise and I was planning on getting to her quilt after I finished the three for my children that I am working on right now. I feel pressured although she has not asked for it in a specific way. It's hard because, ironically, I started quilting to get rid of all the pink fabric my girls "outgrew" and she LOVES pink. My response has been that I love her, and someday I hope to make her something. I also know that when I do get a round to-it, she will be over the moon with joy.
I would suggest saying no - give all the reasons if you have to - You could even tell The people who are asking the truth, that you are just so overwhelmend and would love to but you just can't right now. And then hopefully those who DO receive will be properly surprised and happy. (hopefully)
Oh - and then give thanks to God that you have been endowed with such gifts that you can give pleasure to people!
