There are some wonderful lists out there to help you along with machine knitting!  My first machine was the Bond Incredible Sweater Machine.  I seen it on an infomercial and just had to have it!  I got it for Christmas and got it home and found that I couldn't knit an extra large sweater without an extension......... so back to Walmart and bought a second machine!  Then I lost interest because I just couldn't understand and didn't have anyone that could help me.  This was in 1994.  Well, when I got the internet in 1997, I found a email group!!  The Bond List  A truly wonderful list with all kinds of help!!  A lady named Marie, now my 'bonding buddy' walked me through my very first sweater!  And away I went!!!!!!!!!!!  Then the 'want' occured for more machines and that is how the other two came about!  Another wonderful list to be on is KnittingMachines.  I learned everything from these lists and continue to learn from them.  I am in no way, shape, or form an expert........I just love to machine knit!
