You have said the shop owner and the others in the group are nice and helpful so continue-how lucky to have a nice group. Do the best you can and learn as you go. Sure you are more likely to have imperfections than the more experienced in your group but one day you will have the opportunity to be the more experienced one and get the chance to help someone else. So, when you are all finished, bring in a box of chocolates to share as a thank you for all the help and encouragement you have received. Looking forward to seeing your progress posted here.
